I have put all but one of the above books on reserve at the Math-Stat library in the basement of Sidney Smith. (The university doesn't currently have Zimmer's book. It's a lovely book and costs only $29.54 at amazon.ca) You cannot check the books out --- you have to use them while in the library. The library's hours are Monday to Friday, 9:00-5:00. Please let me know if the restrictions on their use is a real problem for you. Looking to buy used books? I've had good luck with abebooks.com.

Your course mark will be based on homework (worth 20%), three term exams (worth 15% each), and one final exam (worth 35%).

*Advertisement* If test-taking generally makes you nervous, have a look at the test-taking brochure from the University of Illinois at Urbana-Champaign. They also have brochures on other aspects of student life --- have a look --- they're soundly written. *Advertisement*

    Your third homework assignment, due Friday October 4. Here are the solutions. Note: there's a mistake in the solution to problem 5a. Because the matrices are _real_ valued, we cannot diagonalize when the eigenvalues are complex. If the eigenvalues are a +/- i b, then the reduced form of the matrix will be A_11 = a, A_12, = b, A_21 = -b, A_22 = a.

    See the Tietze Extension Theorem in Action! Just save the file tietze_extension.m in your home directory, start up matlab (in your home directory) and type "tietze_extension" at the prompt. If you're a hacker, open it up and change the function f and the number of approximants and whatever...

    See the Stone Weierstrauss approximants in Action! Just save the file stone_weierstrauss.m in your home directory, start up matlab (in your home directory) and type "stone_weierstrauss" at the prompt.

    Here is an example of a space X which is isometric to its second dual X^**, but which is not isometric with X^** when you use the natural mapping from X to X^**. The example was discovered by R.D.James and published in 1951.

    Your seventh homework assignment, due Monday, December 2, is from Kolmogorov and Fomin: page 171 #12, page 183 #8, page 194 #7 and #9, page 205 #2 and #3.

  • Lecture Notes: Nov 25, 2002.
  • Lecture Notes: Nov 27, 2002. Caveat! Kolmogorov and Fomin toy with our emotions --- they introduce "the weak topology on L*" in section 20.3 and then in section 2.4 they tell us... really, the topology in 20.3 is the weak* topology on L*, and now we're going to define the weak topology on L*. So in these notes, my references to the weak toplogy on L* are really the weak* topology. (All of this was explained in class.)

    There will be no class on Wednesday December 4. I'll schedule a make-up class later. There will be no office hours on Monday December 2 or Thursday December 5.
  • Lecture Notes: Dec 2 and Dec 6, 2002.



  • For the Spring semester, class will meet twice a week instead of three times a week. Starting Monday January 6, we will meet on Mondays 12:40-2:00 in SS 5017A and on Wednesdays 12:10-1:30 in UC 67. We have 5 1/2 hours of class time to make up: I deferred class four times in the fall (Oct 9, Oct 11, Nov 15, Dec 4) and will defer it once in the spring (Jan 22). So we have five and a half hours of classtime to make up. I will do this by teaching 12:10-2:00 on the following eleven Wednesdays: Jan 15, Jan 29, Feb 5, Feb 12, Feb 26, Mar 5, Mar 12, Mar 19, Mar 26, Apr 2, Apr 9. Note: this is every Wednesday in the Spring semester except for Jan 8 (second term exam), Jan 22 (class deferred), and Feb 19 (reading week). So the effective schedule for the Spring semester is M 12:40-2:00 in SS 5017A and W 12:10-2:00 in UC 67.

    Extra office hours before final exam The final exam will be on Friday May 2 from 10 am to 1 pm in SS 1083. You're allowed a "cheat sheet" for the exam: 8.5" x 11", with writing on one side. You can put definitions and statements of theorems on it. No proofs or sketches of proofs or counter-examples. You'll hand the cheat sheet in with your exam. If you have specific questions about what's fair game for the cheat sheet, please email me.

    Ching-Nam Hung will have twenty hours of office hours the week before the exam. His office is SS 4052. His office hours will be: Friday Apr 25 1-5pm, Monday Apr 28 1-5pm, Tuesday Apr 29 2:30-6:30pm, Wednesday Apr 30 9am-1pm, and Thursday May 1 9am-1pm.
