Appointments: This is the time of the year when we consider applications for the various tenure track positions - this year we have positions in Math. of Finance, Geometric Functional Analysis, Mathematical Biology and Actuarial Science. Alexander Muermann was interviewed last week for the position in Math. of Finance and it is very likely that we will offer him the position at Assistant level. His file is available to look at in Valerie's Office. The short list of three candidates to be interviewed for Geometric Functional Analysis has been submitted to Dick Peter for his approval. The candidates will most likely come to give talks during the period mid-February to the end of the first week in March. This will be followed by the closing date for the Mathematical Biology position where we have already a couple of very strong candidates, so the position is likely to be filled.


This leaves us with the position in Actuarial Science; a senior scholar from the Steklov Institute has expressed interest in coming to Canada. He is presently the Vice President of the Russian Actuarial Society and has written several books on Mathematics of Finance as well - a couple of these have been translated into English. I have asked for more information (including letters of reference) and, if he meets our expectations, then we will invite him to visit the Department.


Space Issues: I was hoping to see Wayne Hansen's proposal to the Academic Planning Committee, but it has not yet arrived. (Wayne is the Space Planning Officer, Capital and Strategic Planning Services, Operations and Physical Resources). We had submitted our request through Dick Peter in June 1999! From the preliminary version sent to us, we expect Wayne's proposal to contain an increase from 2635 m˛. to 3,650 m˛ (these numbers do not include the 43 m˛ "Math. Remediation" class room in Education South; space for this purpose will increase to
80 m˛), giving us the entire top three floors of CAB. This will also enable us to lock the fourth floor entrances in the evenings and weekends - a mixed blessing. If  you wish to change your office then please put in your request to the internal committee consisting of KC Carriere, Bryant Moodie, Ron Bercov and Rick Mikalonis.


Joint Meeting/Picnic with Math. Stat Dept. U. of Calgary: Last November Ted Bisztriczky, Chair at Calgary, and I talked about getting the Faculties of the two departments to know each other. The Statistics groups meet on regular basis and it is desirable to have this extended to all faculty members of the two departments. One possibility is to have a common picnic in the Red Dear area; another possibility is to alternate between Calgary and Edmonton. We are thinking of the summer period for such a gathering. Let me have your views/suggestions.

The members of the AMI held a meeting in December at which two major changes were discussed. Among these was the decision to not have the Director of the AMI also serve as Principal Editor for the Canadian Applied Math. Quarterly. This will free up the AMI Director's time to work on other projects. The other major change is to integrate the AMI office space with the PIMS office space as soon as is practicable. The AMI space is underutilized at present--in fact the AMI is more of a virtual entity (love that e-world jargon!) than a real estate holding entity. The plan is to have a small office space for CAMQ and the rest of the AMI space will be used by PIMS for post-docs, visitors, and any other needs. There will be a need for an AMI Director's desk and filing space within the PIMS space. This will allow the AMI director and the PIMS Director to coordinate all applied math. activities without overlap.


Some of the above changes will require a mail ballot.


On other fronts, the AMI Director is now managing the IIP (Industrial Internship Program) for mathematics and statistics. I have been working with Kevin Websdale in the Faculty of Science Office. We have about two students presently involved, and another three who are seriously interested. These students spend 6 months to a year working for a salary, then return to their studies. They must file a report on their experience before credit is granted for taking part in the IIP. The program is especially popular with our Specialization students. There is no problem finding places for them to work. Right now, Stats Canada is pressing us hard for a stats. student to do an IIP internship with them. We also have demands for students with an interest in modelling, especially ecological and communications (different firms!).

News from the other side:


Marvin has left us for the greener pastures and bluer skies found by those studying the Earth and Atmospheric Sciences. The last week of January was his last with us. I'm sure we all wish him well there. Finally though, an EAS sysadmin who knows the joys of SSH.


For those people cursing my name every time they try to ftp in (or do other things that the firewall breaks) most of your trouble should be over. The firewall now has a feature similar to the CNS labs, such that once you authenticate to it, you're granted access as if you were on the LAN. To make use of this feature, simply ssh into 'math-gw.math.ualberta.ca' and enter your vega userid and password. That's it. FTP, X, and all that other stuff should work. Please do not do this from a multi-user system (GPU for example).


I'm glad to say that the last few email viruses were handled well, people just deleted them without spreading them around. I have updated the intrusion detection system to watch for the latest round of them. This makes it so much easier to control the spread and to disinfect. We've also purchased a 100-user license of ZoneAlarm Pro, which we can install on windows machines. Z.A.P. offers the usual personal firewall features as well as the ability to filter viruses out of your email. Let me know when is a good time to install it on your machines. We can also sell you a license for home use for about 25% of the retail cost - this is a wise investment for those of you with cable modems and other broadband internet solutions.


Currently we're getting at least one scan ever couple of hours from someone trying to break in; we average 4 or 5 actual break-in attempts daily. The latest round of attacks have been aimed at people with FTP servers, print servers, and portmap/rpc.statd/nfs users. This is just the sort of thing that the firewall was meant to block. Also in security news this week, I received my GCIA certification - GIAC Certified Intrusion Analyst. For more details about this certification check http://www.sans.org/giactc.htm

The MITACS-PINTS centre is happy to announce that we have a new corporate sponsor. Acoustic Positioning Research (APR) is sponsoring us to help them improve their tracking system which is used in the performing arts. APR produces lighting systems in which a spotlight can automatically follow a performer, and systems in which events can be triggered by the location of a performer. APR is working with the MITACS-PINTS centre to use our non-linear filtering techniques in order to improve tracking and prediction capabilities of their systems.

The Chair Selection Committee is soliciting formal questions in advance from the members of the Department.




  VII.     PIMS Graduate Studies 2001


Jim Muldowney


The Pacific Institute for the Mathematical Sciences Graduate Student Information Seminar was again hosted by ourselves and the University of Calgary on January 9-12. Twenty-four top fourth year undergraduates in mathematics, statistics, and computer science from universities all across Canada arrived in Calgary on the Tuesday afternoon.

Students had completed the Calgary portion of the schedule by Thursday morning and departed by bus to Edmonton. Dr. Dick Peter, Dean of Science, and Dr. Peter Steffler, Associate Dean of Graduate Studies & Research, along with faculty and graduate students from the departments of Computing Science and Mathematical Sciences welcomed them to the U of A campus at a banquet at the Faculty Club. Dr. Bryant Moodie, U of A PIMS Director, gave a brief account of PIMS and its particular relevance to graduate studies in the mathematical sciences.

Friday morning activities were kicked off with a presentation by Dr. Bob Moody on ‘Graduate Studies in Mathematical Sciences: 2001’. Dr. Jim Hoover (CompSci) talked about ‘The relationship between theoretical computer science and “standard” mathematics’. Presentations on graduate studies at PIMS universities were given by Dr. Denis Sjerve (UBC), Dr. Randy Sitter (SFU), Dr. Lorna Stewart (U of A) and Dr. Jim Muldowney (U of A).

After a lunch with local CS and MathSci faculty and graduate students, the visitors had a full afternoon of small group meetings, interviews and tours scheduled to address their individual interests. Over 100 meetings with local researchers and with the representatives of the other PIMS sites were arranged by PIMS staff Martine Bareil and Lina Wang.

A farewell party and supper was held at the Varscona Hotel on Whyte after which some participants were said to have explored the attractions of Whyte Avenue late into the evening.

A well-deserved ‘thank you’ to the many graduate students, staff and faculty who gave generously of their time and efforts to make this an extremely worthwhile exercise for all concerned.






Alvin Baragar


The following is a slightly condensed version of the first part of an article that appeared in Folio in 1982. This part deals with the early years of the Department. Two further parts are planned for future issues.


The faculty of the Department has expanded from one man, Muir Edwards in 1908 to fifty-four full-time members in 1982. In that time, the constituency served by the University has evolved from an agriculture-based, pioneer community to the present multifaceted society. The mathematical requirements of the constituency have also changed. Let me introduce some of the distinguished men who have attended to the community’s mathematical needs, and tell you how a diversity of research efforts and accomplishments have come to complement our traditional teaching role.


The history of the Department till 1982 can be divided in a natural way into three eras by the years 1947 and 1961. The first coincides with the tenure of Ernest Sheldon as head of the Department and is characterized by the implementation of Henry Marshall Tory’s vision of a university devoted to excellence in the provision of a general, post-secondary education to the young people of Alberta. By 1947, however, technical developments generated by World War II were changing society. The University responded by developing courses to prepare its graduates to cope with this more complex way of life. Sheldon was succeeded by John Campbell (1947-54) and E.S. (Frank) Keeping (1954-61) who guided the Department through a time of dramatic growth. During this period, a net increase of more than one member per year brought the number of faculty members to 23 in 1962.


The beginning of the third stage was marked by the award of a Ph.D. degree to S.G. Mohanti in 1961 for a thesis in Statistics, supervised by T.V. Narayana. Since then, research has become an increasingly important part of a Department member’s responsibilities. The administration of the Department during these years has been conducted by Max Wyman (1961-63), Leo Moser (1963), Lloyd Dulmage (1964-66), Leo Moser (1966), John McGregor (1966-70), Waleed Al Salam (1970-71), Sudish Ghurye (1972-76), Amram Meir (1976), Murray Klamkin (1976-81) and Jack Macki (1981-87).


During the earliest years, Tory assisted with the teaching of mathematics. In 1910, he appointed Sheldon as professor and head of the Department. Sheldon was an exemplary professor of his day who gave willingly of his time to advise and direct students, and he was well remembered by generations of students for presenting interesting and amusing lectures. In 1913, S. Killing was appointed as the second full-time instructor in the Department, but his academic career was soon interrupted by the war. His distinguished record of service overseas included a stint with the Intelligence Department. He returned to the University in 1919, and by 1921 he was promoted to professor. He loved sports and was a brilliant conversationalist, traits that made him popular with students and staff alike. Unfortunately, his potential contribution to the University was lost when he died in an accident on a Nova Scotia Lake in 1923.


With the end of their military service, two more men who were to give many years of service joined the Department. A former student, Alex Cook, joined the faculty in 1918. Even though he was teaching 15 hours per week, he found time to complete the requirements for an MSc degree from Harvard (1923) and a PhD degree from Chicago (1929). He left the Department in 1951 to become Director of Student Advisory Services. Following services in the Artillery, J.W. Campbell, who was apparently the first staff member to continue to do research following his appointment, came on staff (1920). His principal interests were in astronomy and mechanics; most of his papers were analyses of the shape of hanging, flexible cables under various conditions of load and temperature. In 1941, fully realizing the danger of negative predictions of the future, he published a paper in which he concluded that a rocket trip to the moon and back would be impossible. His formulae were correct; his prediction failed because he could not envisage a fuel that would yield an acceleration of more than 2 g.


In 1929, the Department grew to four with the arrival of Frank Keeping, a mathematical physicist with an interest in statistics. He developed a relatively advanced course in statistics and his notes were eventually expanded into a highly regarded text on Statistical Inference. Many years later (1971) he produced a short history of the Department, from which much of the information for this article has come.


The world was plunged into the great depression, and the drought in western Canada that accompanied the financial disaster elsewhere assured particularly hard times for Albertans. University salaries were reduced by 10% (Assistant Professors’ salaries dropped from $2500 to $2250) and, when Social Credit came to power, depreciated further by the substitution of scrip for some of the money. These times were much more difficult for other parts of the community than they were for professors, but still, students attended the university. Despite of the small size of the Department, there was an honours program that attracted several students. In 1931, ten students were working towards an honours degree.


Max Wyman graduated from the program in 1937 and, as was customary, was counseled to attend a good American university for his PhD, which he received from the California Institute of Technology in 1940. He began his distinguished service to the University of Alberta in 1943, where his research continued, as was attested by the opening sentence of a paper that appeared in Reviews of Modern Physics in 1946: “Mr. Max Wyman has drawn our attention to several mistakes in the formulas of the second part of our paper”. The authors were A. Einstein and E.G. Strauss.






                 i.          Colloquium (Hans Brungs)

a.     Christmas Party


The Department held its annual Christmas in the upstairs dining room of the Faculty Club. Attendance was over one hundred, one of the largest parties in the Department’s history. After Dr. Rhemtulla conveyed season's greetings, he introduced retired professor Alvin Baragar. Dr. Baragar presented a history of Edmonton, the University, and the Department, complete with a large collection of slides. It was fun to see the evolution of Edmonton from a city with muddy lanes for streets into a modern city over a century. And those among us who are quite ancient really enjoyed the pictures of ourselves and colleagues when we had fewer wrinkles and pounds. Dr. Baragar's after-dinner talk was followed by a draw for door prizes. In order to avoid complaints about bias, we had Valerie draw the numbers from a box held by Rick Mikalonis. Of course, Rick's name was drawn, and an investigation has been launched. The prizes were either bottles of Chivas Regal or boxes of Callebaut chocolates. For some reason, all the bottles of Chivas went first. Afterwards the grad. students demonstrated their dance moves for the faculty, and marks were secretly awarded and entered on transcripts.



b.     Engagement announced


Sandra Strawford, in the general office, got engaged on Dec. 11th to Wayne Salmon. They will be married on

June 29, 2002. Congratulations to the happy couple.



c.      Birth announced


On January 12 a son was born to Georg Peschke and his wife Soledad. The baby, named Tomas, weighed 3.4 kg. Congratulations to the happy parents.

d.     Promotions and Tenure


Congratulations also to Yanping Lin on being promoted to Full Professor and to John Bowman, Mike Kouritzin, and Bruce Sutherland on receiving Tenure. The recipients hosted a very successful party at the Faculty Club on

January 19, 2001.



e.      Continuing Appointments


Finally, we congratulate Henryk Kolacz and Eric Woolgar on receiving continuing appointments in the Department.





A sample of mathematical humour found on the internet:

A doctor, a lawyer and a mathematician were discussing the relative merits of having a wife or a mistress.
The lawyer said: For sure a mistress is better. If you have a wife and want a divorce, it causes all sorts of legal problems.
The doctor contradicted him: It's better to have a wife because the sense of security lowers your stress and is good for your health.
But the mathematician contradicted them both: You're both wrong. It's best to have a wife and a mistress so that when the wife thinks you're with the mistress and the mistress thinks you're with the wife --- you can be in your office and do some mathematics.
