Abstract: The variety of a finitely generated kG-module is a closed homogeneous subvariety of the maximal ideal spectrum of the cohomology ring of a finite group G with coefficients in an algebraically closed field k of characteristic p>0. I will give some basic definitions and properties of varieties in group cohomology. Then I will present some results on filtration of modules related to varieties.
