Title: Galois module structure of varieties over the integers

Abstract: Let X be a projective algebraic variety defined over the integers which supports an action of a finite group G.
If F is a coherent sheaf over X with compatible G-action, the cohomology groups H^I(X, F) are G-modules
and we would like to determine their structure. We will give an overview of some history and describe various results and conjectures around this problem.
