Description
Commutative Algebra seminar.
Speaker: R V Gurjar.
Affiliation: IIT Bombay.
Date and Time: Monday 23 September, 3:30 pm - 5:00 pm.
Venue: Room 215, Department of Mathematics.
Title: Paul Robert's Theorem.
Abstract: Let a finite abelian group G act on a normal local domain R
with residue field of R of char. 0. Assume that R^G is a UFD. Then R is a
free R^G- module. In particular, if R^G is regular then R is Cohen
Macaulay.
We will start preparation for P. Samuel's descent theory.
