Course notes

Be prepared to take careful notes in class, as no set textbook will be used.

You are welcome to use the fine notes by Dr. Runde (PDF, 0.7MB) for background reading. Be aware, however, that notation and terminology in these notes may differ from the ones used in class.


Material covered in class (Course Diary)

I plan to keep an up-to-date list of the topics, examples etc. covered in class.

Three words about cheating:

    Don't Do It !!

Midterm test

Two midterm tests will be held on Friday October 23 and November 27, 2019, respectively, in class.

Some details about the first midterm:

  • Duration: 50 minutes.
  • Material covered: up to, and including Example I.60, i.e., the Hahn-Banach theorem and some of its consequences.
  • NO textbooks, notes, calculators, formula sheets etc.!
  • NO cell-phones, laptops, or other electronics!
  • Please bring a valid ID with you.
  • Good luck!

To help you prepare for the midterm test, a practice version has been posted on eClass - the real test will be very similar.

Some details about the second midterm:

  • Material covered: up to, and including Corollary II.29, with an emphasis on inner product spaces.
  • All other details (50 min duration, no books or electronic aides, etc.) are exactly as on the first midterm.
  • Good luck!

To help you prepare for this test, a practice version has been posted on eClass - just as on midterm I, the real test will be very similar.

Final exam

The final exam will be held on Tuesday, December 17, 2016 at 2:00 pm, in CAB 281.

Some details about the final:

  • Duration: 2 hours.
