The honors course on Algebra will treat, among others, groups and the three isomorphism theorems, group actions, and the three Sylow theorems. The prerequisites required for this course are covered in Math 115A.

The course will have weekly classes on

  • Mondays, Wednesdays, and Fridays in MS, room 5148, from 1:00 to 1:50 pm.

The book we will be following is Lectures on Abstract Algebra by Richard S. Elman. We will be covering material in Chapters 1, 2, 3, and 4. The recommended reference books are Algebra by Thomas W.

There are many resources available for a student at UCLA, I encourage you to use them and make the most out of them. Here are some materials specific to this course:

  • The open office hours at the Student Math Center can be found here.
  • The mathematics software Sage can be found here.
  • Four standard tricks to show that a group is not simple can be found here. This was made by Tai-Danae Bradley.

I also encourage you to form study groups with your classmates. However, please keep in mind that you will only learn how to do the exercises if you try them on your own: without trying, looking up the solutions or copying others' work is absolutely useless.
