cohomology II”

ERGUN YALCIN

__Abstract: __I will continue my
previous talk on Smith Theory and Bredon Cohomology. I will first remind the audience the definition
of Bredon cohomology. Then,
I will prove some classical theorems by P. Smith. These theorems on fixed point
sets of p-group actions on spheres and on discs are usually referred as Smith
theory. This alternative approach to Smith Theory via Bredon
cohomology is due to Peter May. I will also discuss
some possible further applications of Bredon cohomology to fixed point theory.

All are most
cordially invited. The Algebra Seminar will start 10 minutes after the topology
seminar. There will be a tea in between these two seminars.

Date : October 5, 2009 (Monday)

Time : 13.40-14.30
