General Prerequisites: Rings and Modules is essential. Representation Theory and Galois Theory are recommended.
Course Overview: Amongst the most familiar objects in mathematics are the ring of integers and the polynomial rings over fields. These play a fundamental role in number theory and in algebraic geometry, respectively. The course explores the basic properties of such rings.
