12/05/2010  Due to an emergency, I have to cancel today's office hours scheduled for 1-2:30pm. I will try to reschedule for later in the day, so please check back here. I will try to make an announcement today around 4:30pm. I am sorry about this last minute change, but it is out of my control.

12/02/2010  Practice problems for the final.

12/01/2010  Solutions to the worksheet problems.

11/29/2010  Homework solutions are posted on webct.

11/19/2010   The homework solutions will be posted on webct from now on (starting with hw6; hw1-5 are on Ryan's webpage).

11/09/2010   I finally posted the solutions to the first midterm. They are on the exam page. But I will NOT post solutions to the makeup problems.

11/02/2010   I updated the midterm scores on webct. The new median is 64.9.

10/26/2010   The makeup problems are due by 5pm, Friday 10/29 in the usual homework box.

10/22/2010   Errata for the makeup problems: in problem #3, it should be "xR, x ≠ 1/2"

10/22/2010   I posted the midterm scores on webct. As I announced today in class, the median score was 44. Thus, I decided to give everyone a chance to make up half the points they lost on the score. E.g. if someone had a score of 50/120, (s)he can get up to 35 points back, raising the score to 85. In order to do so, you have to write up solutions to the problems here. I will assign partial credit, so even if you don't do all the problems. you can still raise your score. In order to help you study, here's a review of the concepts covered so far.

10/20/2010   Office hours today are cancelled.

10/18/2010   Due to space constraints, we have 2 exam rooms for the first midterm. Please make sure you go to the right one, according to the initial of your LAST NAME.

Description: This is the first undergraduate course in abstract algebra. Our main topic will be group theory. Compared to Math 100A, this course goes more slowly, is somewhat less proof-oriented, and spends more time on applications of the theory. For most variations of the math major which require a course in algebra, 103A suffices. If you are considering graduate study in mathematics, however, you should take Math 100A instead.

Prerequisites: Math 109

Textbook: J. Gallian
Contemporary Abstract Algebra, 7th ed.
Brooks Cole
