"On cohomology Groups of

Semidirect Products"

By

Ayşegül Tekin

(Bilkent University)

Abstract: In this talk, we will discuss cohomology
groups of semidirect products $\Gamma=L \rtimes G$, where G is a finite cyclic gorup
and L is a finitely generated ZG-lattice. I will state a conjecture of A. Adem on the cohomology of these
groups. Then, we will discuss the method of N. Petrosyan
and Wall's theorem which are used to construct counterexamples
for this conjecture.
