Course description

This class will cover groups, rings, and ideals. More explicitly: Groups acting on sets, examples of finite groups, Sylow theorems,solvable and simple groups. Fields,rings, andideals; polynomial rings over a field; PID and non-PID. Unique factorization domains.

It will be a fast-moving, high-workload class. Most students interested in this material will find Math 109 more appropriate. This is also a Writing in the Major class.
