November 25, 2002: On Problem Set 10, you might want the following definition: A group G has a non-trivial center if the center of G contains any element of G other than the identity. October 29, 2002: Problem Set 7 will be due on Tuesday, November 5 instead of Friday, November 1. September 25, 2002: Let's omit Problem 5 from Problem Set 3, since we haven't yet covered Theorem 4.4. I'll include that same problem in a future problem set, probably the very next one. September 18, 2002: My office hours today will be 4:30 - 5:30 instead of 3:00 - 4:00. September 10, 2002: We will meet in 402 Clapp on Tuesdays and Thursdays for the rest of the semester. On Fridays, we'll continue to squeeze into 422 Clapp until we can find an alternative. September 3, 2002: The textbook for the course is Contemporary Abstract Algebra by Joseph Gallian, fifth edition, Houghton Mifflin, 2002 (ISBN 0-618-12214-1, if you're interested). There were 19 copies on the shelf at Odyssey this morning. You can also order it on-line from Amazon/Borders, Barnes and Noble, or Varsity Books (and probably elsewhere). The on-line prices I found were about the same as the Odyssey price, and didn't include shipping.
