Editor’s comments: This is the second of this year’s departmental newsletters. The editor relies on being supplied by its readers with newsworthy items of current interest in this Department. The amount of information received determines the frequency of this newsletter. Please send any correspondence for future issues to gludwig@gpu.srv.ualberta.ca, with “Newsletter” in the subject line.
I. CHAIR’S REPORT TO THE
DEPARTMENT
Teaching is in full swing and it keeps us too busy to spend time on discretionary activities! My comments will be brief for this reason.
APO: Richard Mikalonis is the departmental Administrative Professional Officer. He takes over the administrative chores of the Department from Ivan Baggs who will return to being a regular teaching faculty member. Please welcome Richard to the Department.
Associate Chairs: With his return to regular teaching, Ivan will retire as Associate Chair  Administration starting January 1, 2001, and the position will be eliminated. However, we plan to create the position of Associate Chair  Research. The duties of this person will be to enable the Department, faculty members and students to achieve greater awards and grants by supplying us with relevant information and assistance in the application process. Department of Biological Sciences has such a position. I would like to hear your comments and suggestions on this matter. The initial appointment may have to wait until the next Chair gives his/her approval.
Positions: As you know, Mark Lewis has been nominated for a Senior Canada Chair and if all goes according to plan he will join the Department on July 1, 2001. In addition, we will try to fill four other positions, one in each of the following areas: Actuarial Science, Mathematics of Finance, Geometric Banach Space, and Mathematical Biology. All four are regular positions, but the last two were created to go along with the nominations of Nicole and Mark as Canada Research Chairs. This is a commitment the university has made to build strength in the areas of Senior Canada Chairs.
Mathematics Courses for High School Teachers: The Edmonton Public School Board now requires all Junior and Senior High School mathematics teachers to have 18 credits in proper mathematics courses. This naturally puts additional demand on us. Beginning January 2001, we shall offer evening sessions of Math 160 and Math 222 to enable inservice teachers to upgrade themselves. Andy Liu has put in a lot of effort in this program and can provide additional information.
Some New Space: We now have the lab space on the fourth floor vacated by Computing Science. Our plan is to use this space for one term to bring back the graduate students who are presently in Temp. Lab. The move will take place during the Christmas break. Once we get the rest of the requested space (by May 2001?) this lab space will be equipped with 20 stations for use by graduate students, postdoctoral fellows and visitors. We are also working on getting the postdoctoral fellows who are presently in Temp. Lab. back to CAB.
Department Dinner Party: Please try to make it to the Department Dinner on December 2nd in the Faculty Club. Tickets from Sandra in the General Office.

Enrolment in our Honors program is 33 students this year, up from 16 last year. In our Specialization programs, enrolment is 78 students this year, up from 72 last year. Enrolment in first year Honors Calculus, Math 117, was 59 as of the beginning of October; this is the highest in over 15 years. Last year's enrolment was 27. Enrolment in Math 217 is 24; this is the highest since 1992. Last year we had 13.
By now, I'm sure that we've all heard of Sherwood's departure to Yotta Yotta, a company doing highly salable network storage. Sherwood's doing much the same as he was doing here  fixing things, rolling out new stuff  and from the last time I had a chance to talk to him, they had plenty of things to occupy his time. This means that suddenly we're a man down. To that end, Marvin's task list and my task list have grown by about 50% each. By all reasonable estimates, the earliest we're likely to see a replacement for Sherwood is February. Marvin and I would like to ask for your patience and understanding while we try sort this out.
Network
news:
The first two servers in our vegareplacement cluster have arrived, along with four shiny new application servers. Integrating them into the existing network architecture without breaking anything is turning into a bigger problem than I thought. Mail services, for example, are somewhat tricky due to the fact that we receive and store mail on one machine and read it from a whole bunch of others.
We’ve also installed a new router. This machine should make firewalling a fair bit easier and faster. There are still a few minor issues to be resolved with it, but the status quo has mostly been restored, with improvements to come in the near future.
Some of you may have noticed my absence during the second half of October. I was away at the Network Security 2000 conference. I took the intrusion detection track, which specialized in detecting attacks (over the network) before they get too far. While I don’t mind the overtime, I’m sure that no one likes to have their computer out of service for a few days because it got broken into. Besides bringing home over 10 kg of textbooks, I also picked up some very good information concerning things that we should be doing to improve security while not breaking anything. When you think about it, improved security systems lead to better service; a highavailability system will withstand a random fault at a random time, whereas a secure system will withstand pathological fault at the most inopportune time.
To put the idea of security causing reliability into perspective, this means that things like banner ads and spam aren’t permitted to waste resources, and netscape zombies don’t clog the servers  a good thing by all accounts. This also means that with proper filtering, desktop machines aren’t vulnerable to a raft of remote denialofservice attacks. It only takes one packet to hijack a network connection or to crash a box, and sadly, these sort of attacks are nearly trivial to prevent. Finally, traffic analysis can be used to determine what machines need an upgrade the most  if the mail server seems to be constantly generating the same amount of traffic, this might be an indication that it’s overloaded and needs to be moved to a more capable box.
Since its launch in the spring of 1999, the MITACSPINTS Centre of Excellence, based at the University of Alberta, has made several advances in filtering theory.
Filtering deals with finding a signal which behaves according to some stochastic process, based only on noisy, partial observations of the signal, and a model of the signal’s behaviour. Filtering has applications in many different areas such as mathematical finance, search and rescue, manufacturing, narcotic smuggling prevention, and air traffic control, and has attracted the attention of companies such as Lockheed Martin, VisionSmart, Stantec, and Acoustic Positioning Research.
The MITACSPINTS centre researches many types of nonlinear filters, such as convolutionalbased approaches, Markov chain filters, and particle filters, and investigates the computational effectiveness and realworld applications, in addition to the theoretical properties, of these methods.
Recently, as a result of work by Dr. Michael Kouritzin and students David Ballantyne and Hubert Chan, the centre has introduced a filter which is capable of smoothing, that is, filtering the entire historical path of a given signal in an asymptotically optimal way. The only other known filter with this capability was developed by members of the centre and the results have been submitted for publication. This method works recursively and is extremely computationally efficient.
In certain situations, an exact model for the signal is
not known. Often, the model may contain unknown parameters which cannot be
determined beforehand. In order to solve this problem,
Dr. Michael Kouritzin and Dr. Ruisheng Li developed a method based on particle
systems to perform combined parameter and state estimation, and Hubert Chan is
developing computer simulations to test its practical effectiveness.
Postdoctoral fellows Dr. Hongwei Long and Dr. Wei Sun have been working on random environment modelling, which will allow us to develop more realistic signal models, while students Michelle Prefontaine and Calvin Chan are applying convolutionalbased methods to financial market applications using a meanreverting volatility model. Work is beginning on estimating the parameters to be used in the models.
The centre has been featured in articles in Silicon Valley North, the Globe and Mail, the PIMS newsletter, NSERC success stories, and the Report Magazine. Members have given talks at the University of Wisconsin at Madison, the University of Minnesota, the MITACS annual general meeting, and at the AeroSense conference.
VI. REPORT FROM THE
BIOSTATISTICS RESEARCH GROUP
(i) The Training Consulting Centre (TCC) was established in April 2000 with funding from the Department of Mathematical Sciences (1) to provide job training of our graduate students and (2) to improve quality of research done at the University of Alberta.
The services are available to all University of Alberta faculty, staff, and students concerning statistical questions related to research at no direct cost to the clients. This studentoperated centre has served virtually every faculty on campus to date. The student consultants gained significant confidence at consulting with nonstatistically oriented clients, developing friendship across campus. Most importantly, it played a major role in planting two recent statistics graduates with fulltime jobs! The TCC welcomes three new consultants: William Midodzi, Meseret Hailemariam, and Amrit Shresta. The current consultants Abdulkadir Hussein, Alex de Leon, Melody Gahrhamani, Xiaoming Sheng, and Rong Huang (the Coordinator) continue to assist clients needing their statistical expertise. More information can be found at: www.stat.ualberta.ca/~brg
(ii) We welcome Dr. Saumen Mandal (PhD. Statistics, 2000, University of Glasgow, U.K.) who joined us as of November 1, 2000. He will be working with K.C. Carriere as a postdoctoral fellow. His area of research is in constructing optimal designs.
(iii) Good news to those who wanted to have a one or two day brainstorming workshop on SAS. The Department of Public Health Sciences is organizing a one to two day SAS workshop with CNS. Depending on the number of participants, it could cost $135/student. The software SAS is an essential tool for any consulting statistician. Anyone interested in taking up this opportunity should send email to kathleen.forbes@ualberta.ca who coordinates the time and date for this event.
(iv) Do we need more doctors in Alberta? In Canada? Currently, females make up about 33% of generalist physicians in Alberta, while female medical students make up over 60% of their classes. It was hypothesized that female physicians tend to spend more time with patients and thereby handle fewer patients. Alberta Health and Wellness is concerned that the trend of increasing number of female physicians might create a doctor shortage in dealing with the demand for physician services. Predicting the need has been the focus of a recent project, funded by Alberta Centre for Health Services Utilization Research (PI: KC Carriere). While this research is in progress, we recently completed a project comparing the effect of outsourcing cataract surgery to private clinics. The general conclusion is that while private clinics definitely have shorter waiting times, there are other primary factors that determine waiting times. Many statistical issues arise in trying to solve these real world problems; some find an approximate solution relatively easily, while others get very rigorous treatment in an attempt to find a solution.
VII. THE HIGHSCHOOL TEACHERS
UPGRADE PROGRAM
It should be mentioned right from the start that this requirement is not a substitute for the existing program in secondary education with a major in mathematics, or in the mathematics stream of the BEd/BSc joint degree program. The intention is to prevent schools assigning teachers without the necessary qualification to teach mathematics. Up till now, this is often done out of expedience, since there is a perpetual shortage of mathematics teachers.
A special program is being set up between the Edmonton Public School Board and our Department. Evening courses, meeting once a week for three hours, are being scheduled for the teachers. Courses to be offered include MATH 160, MATH 222, MATH 241 and MATH 260 as well as a new course to be introduced later. It is tentatively numbered MATH 164 and titled Higher Algebra, covering material in classical algebra embodied in textbooks such as the one by Hall and Knight, with supplementary material from more modern topics.
The Edmonton Public School Board is paying the tuition for those teachers who have not taken six halfcourses of university level mathematics and are interested in upgrading themselves. Some who are nearing the end of their careers may not be interested in taking advantage of this offer. Their jobs are not threatened; they would simply be reassigned away from mathematics. However, younger teachers may see this as a golden opportunity to improve their portfolio, and an ability to teach mathematics provides much greater flexibility and security against future cutbacks.
A preliminary survey indicated that for each of the five courses offered, at least 70 teachers are interested in taking them. MATH 160 and MATH 222 are scheduled to go in the coming January, with other courses to follow in subsequent terms. Teachers may also take other courses during the summer session.
Planning is under way to host two concurrent international conferences at the U. of A., with themes on Differential Equations and Mathematical Biology, in the Spring of 2002. The first conference is the Fourth Geoffrey J. Butler Memorial Conference on Differential Equations and Population Biology. The past three Butler conferences were all held here at the U. of A., in 1988, 1992, and 1996. The second conference is the Fifth Americas Conference on Differential Equations and Nonlinear Dynamics. This biennial conference has been held since 1994, with the participation of researchers from the United States, Canada, Brazil, Mexico and Venezuela. The first four meetings took place in Mexico (1994), Brazil (1996), USA (1998), and Venezuela (2000).
The
PIMS Thematic Programme in Algebra, called Algebra 2000, took place at the
University of Alberta over a 4week period from June 19 to July 14. The
programme, which was organized by the algebra group at the University of
Alberta, consisted of summer schools and workshops in three areas of algebra:
Lie Theory, Group Theory and Representations, and the Mathematics of Aperiodic
Order. Each area was featured for 2
(overlapping) weeks. The programme was very successful and attracted over 100
participants.
In the first week, the Lie Theory summer school featured 2 series of introductory talks for graduate students. Stephen Donkin of Queen Mary and Westfield College gave 5 lectures on Algebraic Groups and Arturo Pianzola of the University of Alberta gave 5 lectures on Lie Algebras. The Lie Theory workshop in the second week included onehour talks by experts from Europe, United States and Canada on recent developments in the subject. Topics included vertex operator algebras and various infinite dimensional generalizations of finite dimensional simple Lie algebras. Many of the talks, as well as much informal discussion, focused on the increasing interplay between Lie theory and mathematical physics.
The Groups and Representations summer school started in the second week with introductory lectures for graduate students given by Peter Kropholler of Queen Mary and Westfield College, London, Gerald Cliff of University of Alberta, Alexander Olshanskii of Moscow State University, Dan Segal of University of Oxford and Alexander Turull of University of Florida. The workshop in the following week was devoted to hour long talks. Half of these were in representation theory and the rest in infinite groups. Topics included representations of finite groups, profinite groups and Burnside problems.
In the third week of the programme, we began the summer school on Aperiodic Order. This school included four lecture series (a total of 10 lectures):
“Introduction to longrange aperiodic order”: Michael Baake, Universität Tübingen;
“The geometry of point sets”: Jeffrey Lagarias, AT&T Research Labs;
“Tilings and dynamical systems”: Boris Solomyak, University of Washington;
“Stochastic and other directions”: Michael Baake, Universität Tübingen.
These beautifully prepared talks were of a consistently high standard. Because the subject is new and has quite diverse mathematical components, these lectures were enjoyed immensely by students and researchers alike. In addition, Uwe Grimm gave several handson computer demonstrations illustrating the main features of aperiodic tilings.
The final week of the programme consisted of a workshop on Aperiodic Order with 4 to 5 onehour talks per day. The talks from the participants covered the entire spectrum of the subject from the spectral theory, through diffraction, substitution systems, automatic sequences, random tilings, aperiodic Schrödinger operators, and aperiodic approaches to random number generators.
Many of the
participants in Algebra 2000 took advantage of the weekend between their summer
school and workshop to go to Jasper where they stayed at the Palisades Science
Centre. This extraordinarily good bargain provided continued discussions
throughout the weekend and helped enormously to develop the fine spirit of the
entire programme.
Roma Tatchyn
I completed a 16 month internship on
August 31, 2000 with the Department of Mathematical Sciences at the University
of Alberta. I was very curious to discover what opportunities would be available
to me with a science degree specializing in mathematics. I wanted and needed to
learn which and what applications would be expected of me and how to apply them
successfully in the work force.
The position I received demanded several different tasks of me such as updating web sites, creating quizzes, scanning course notes/solutions/assignments and determining optimal methods to display/view/print mathematics on the web.
I discovered several techniques to do this: PDF, TEX, images (created from MathType, Maple or any drawing software) embedded in HTML, HTML paired with Java applets, Powerpoint, Flash, PS and MathML. The latter is still in its preliminary stages and hasn't yet reached its full potential, but it may be very worthwhile to keep track of its progressions.
HTML with Java applets, Powerpoint, and Flash were the main techniques used to create lessons to supplement inclass discussions and/or lectures. Each have positive and negative aspects and can accommodate an instructor in different ways.
HTML with Java applets allows interactivity, easy to understand graphing applets, clean and clear text to supplement the applet. It can amount to a large file size and download time because of the embedded math. images and the time for the Java applet to be enabled.
Powerpoint is of point form style, has basic animation, minimal interactivity and a relatively small file size. Microsoft Powerpoint allows you to convert the presentation into HTML directly through the software so there is no extra effort needed to post the material on the web. This works well for posting course notes on the web.
Flash is a newer method of posting material on the web. It is user friendly. You can create simple and complex animations, it is typically a smaller file size (approximately 100200 K per animation), you can import images or manually create math. symbols in Flash with the drawing tools that Flash supplies. It is not worth using Flash simply for course notes, announcements or any type of lengthy text. Flash is great for creating live graphs to show students exactly how to apply certain mathematical concepts.
I realized how challenging it is to display mathematics successfully on the web and obtain an ideal final result. The several methods available are not complete  but with constantly upcoming newer versions of software and applications you are able to step closer and closer to a desired final result.
I came to Alberta
in 1968 on a twoyear postdoctoral fellowship and joined the regular academic
staff of the Department of Mathematics in 1970. After leaving Alberta in 1995,
I spent two years at Kuwait University and have been at the University of
Nebraska in Lincoln, Nebraska, since September 1997.
The following comments describe some of my impressions concerning mathematics departments with which I have been involved over the last several years. I have not included many remarks about Alberta since, presumably, the readers will have some experience and knowledge of the Alberta environment.
Kuwait University has about 55 faculty members in the Department of Mathematics and Computing Science (Statistics and Operations Research are separate). Most of the faculty members are nonKuwaiti (and therefore on twoyear contracts, which are renewed at the pleasure of the administration). The largest minority of the staff members come from Egypt—prior to the Gulf war, this position was held by the Palestinians and Iraqis). There are also quite a few faculty members from Eastern Europe. Classes are taught in English, although firstyear classes are often taught by Arabicspeaking staff members (to help some of the students over the rough spots). The enrolment is about ten thousand, mostly undergraduate, and mostly women. It seems that many of the brighter Kuwaiti male students go overseas to study, many to the Boston area. Although classes begin at about 8:00 am (SaturdayWednesday), most university offices close for the day by 2:00 pm, and most faculty members leave the campus at that time. Most students are Kuwaiti. It seems that they are often much more interested in a good grade than in mastering the material in the course since, for the most part, they are guaranteed employment after completing their degrees. Decisions taken at the departmental level are made after careful consideration of the desires and wishes of the Kuwaiti staff members (about ten). There is a small graduate program (M.Sc. only), but since most of the students are “locally produced”, it is much better on paper than in reality.
The University of Nebraska, Lincoln, serves about 23 thousand students and the Mathematics and Statistics Department is regarded as one of the top departments in the University, having won the Statewide Teaching Award in 1999 and also received the Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring in recognition of its success in mentoring female graduate students. At the present time more than half the teaching assistants are women (27 out of 50). There are approximately 145 undergraduate math. majors, 58 of whom are women. The Department is home to the American Mathematics Competition which sponsors the high school mathematics competition that leads to the selection of the U.S. Math Olympiad Team. Each Fall, the Department sponsors a Math Day, which involves about 1300 students from more than 100 Nebraska high schools. In addition, several faculty members are involved in the annual All Girls/All Math summer camps for high school girls. The number of faculty is about 3536, about one half the size of the University of Alberta’s. The Department is part of the College of Arts and Sciences and so seems to be not as top heavy with administration as the U. of A. The Department is friendly, has a very hardworking chair, and, by and large, seems to have been spared major problems between the various groups within the Department, which is often not the case elsewhere. Research productivity (the faculty average about 1.5 papers/year) is strongly encouraged, and there is pressure from the administration to apply for external grants. Within the past 3 years, about 75% of the faculty have had some form of external funding. NSF grants are, of course, substantially more difficult to obtain than NSERC grants, with probably fewer than 30% of the NSF applications being successful. It seems to me, however, that the Canadian NSERC program is better than the NSF program since it provides funding for a much larger percentage of staff members—smaller grants, but more flexible.

Seminar on
Mathematical Biology (Gerda de Vries)
About a dozen faculty members, postdocs, and graduate students with an interest in Mathematical Biology meet weekly (Thursdays, from 12:30 to 2:00, in C E 436) to discuss current research projects. The usual format of our meetings is for each of us to give a brief synopsis of what we've been working on since the last meeting. This roundrobin is followed by an extended informal presentation by one of the participants on a topic of his/her choice. Topics range from the theoretical to the applied. Anyone with an interest in Mathematical Biology is welcome to attend and participate. For more information, contact Gerda de Vries, or visit
http://www.math.ualberta.ca/~devries/groupmeetings.html.
iv.
MITACSMMPD Seminar (Gerda de Vries)
The newest MITACS project, Mathematical Modelling in Pharmaceutical Development, led by Jack Tuszynksi from the Physics Department is up and running. Gerda de Vries leads the seminar series. So far, we've had two seminars from our "sponsors": Michael Hendzel from the Cross Cancer Institute spoke about the architecture of cellular nuclei, and Doug Ridgway from Kinetana, a local biotech company, spoke about modelling drug absorption. For more information on the MITACSMMPD project, visit
http://www.phys.ualberta.ca/mmpd/.

Seminar on Differential Equations and Dynamical Systems
(Michael Li)
The departmental Differential Equations and Dynamical Systems Seminar is up and running this semester. The seminar is held every Friday at 2:00 pm in room CAB 229.
Dr. Yuming Chen, who is a Killam PDF working with Dr. Muldowney, gave the first two talks on global dynamics of neural networks with delays. Connell McCluskey, one of our Ph.D. students, gave the next two talks on a mathematical model for infectious diseases with different infectious stages. These interesting talks were followed by an excellent presentation given by Dr. Ming Mei, a postdoctoral fellow working with Dr. Joseph So, on stability of waves for 2X2 relaxation models.
The schedules for the rest of the semesters are:
Nov. 10, Michael Li, “Disease dynamics: a new approach to old models”.
Nov. 17, James Muldowney, TBA
Nov. 24. Gustavo Carrero, TBA
Dec. 1, Jack Macki, TBA
All those interested in attending are welcome. All those wishing to present, please contact Michael Li mli@math.ualberta.ca.
vi.
Seminar on Algebra (Bruce Allison, Benjamin Klopsch)
The Algebra Seminar meets each week on Friday afternoon for 1 hour. The seminar gives local faculty and students the opportunity to give one or two talks on their recent work and interests in algebra. This is valuable for all of us since it allows us to keep in touch with the work that is being done within the algebra group. The seminar also provides a forum for visiting researchers to speak to us about recent developments in their areas.
The speakers in September and October were
Günter Krause (Winnipeg), Benjamin Klopsch (Alberta), David McNeilly (Alberta), and
Keqin Liu (UBC).
The speakers scheduled for November are
Jorgen Rasmussen (Lethbridge), Terry Gannon (Alberta), Jürgen Ritter (Augsburg), and David McNeilly (Alberta).
The talks cover topics from ring theory, group theory, knot theory, Lie theory and number theory.
vii.
Seminar on Differential Geometry (Peter Antonelli)
The geometry (research) seminar has been running weekly for the last 3 or 4 years. Topics are extremely variable, largely because “geometry is everywhere”. Some years there has been an accent on Finsler geometry and also algebraic geometry (Hodge theory). This year, so far, we have had fair attendance, ca. 8 – 10 people, and have had Noriko Yui, Don Stanley, Michael Li, PaulEugene Parent, and Peter Antonelli on topics in, respectively, Algebraic Geometry, Algebraic Topology, differential equations, algebraic topology, and Finsler Geometry and application.
We have scheduled James Lewis, Dragos Hrimiuc, Ioan Bucataru and, possibly, John Bowman for future talks.

Farewell
Charlotte Uhrig joined the support staff of the Department of Mathematical Sciences on May 27, 1999. She advanced to an Academic Personnel Assistant position in the Office of the VicePresident (Academic) & Provost on October 23, 2000. We wish her all the best.
The secretaries said goodbye
To Charlotte with a sigh.
They took her out to dine
Wednesday night, which was devine.
They laughed and reminisced
Of the past year in the office.
They gave her their good wishes
And said farewell with gifts and kisses.

Retirement
The Statistics Centre hosted a
conference in honour of the retirement of Professor Douglas Kelker on September
28. Professor Jack Macki was appointed statisticianforaday in order to open
the conference with some reminiscences
of Doug’s early days in the Department. This was followed by stimulating
lectures by Professors Peter Hooper and Subhash Lele, and by a banquet at the
home of Professor Lele.

HUMOUR
A sample of
mathematical humour found on the internet:
A physicist, an engineer and a mathematician were all in a hotel sleeping when a fire broke out in their respective rooms. The engineer woke up, saw the fire, ran into the bathroom, turned on the faucets fullblast, flooding out the entire apartment, thereby putting out the fire, and he went back to sleep.
The physicist woke up, saw the fire, ran over to his desk, pulled out his CRC, and began working out all sorts of fluid dynamics equations. After a couple minutes, he threw down his pencil, got a graduated cylinder out of his suitcase, and measured out a precise amount of water. He threw it on the fire, extinguishing it, with not a drop wasted, and went back to sleep.
The mathematician woke up, saw the fire, ran over to his desk, began working through theorems, lemmas, hypotheses , you name it. After a few minutes he put down his pencil triumphantly, exclaimed "I have proved that I can put the fire out!" and went happily back to sleep.
