Title: Invariant Theory of Commutative Rings
Abstract: Abstract: Given a group G acting on a ring R, we consider R^G,
the subring of elements fixed by G. It's a natural question to ask what
"good" properties of R are inherited by R^G. Some of these questions were
considered by Hilbert and Noether, and were a motivation to study
noetherian rings. We will discuss some of these results.
This talk should be accessible to someone who's done a first course in
module theory
