"Bredon-Illman Cohomology with Local Coefficients III"

By

TURGUT ÖNDER

(METU)

Abstract: This will be the third of the
introductory talks on Bredon-Ilman Cohomology with local coefficients. This is a cohomology associated to each G-space X, where G is
topological group, with a suitable local coefficient system on X, and it
satisfies all the equivariant Eilenberg-Steenrod
axioms. The main motivation to study this cohomology
is the related equivariant obstruction theory for equivariant sections of a G-fibraton
over a G-CW complex when G is a compact Lie group.

Tea and cookies will be served after the
seminar.
