Computing group cohomology using spectral sequences abstract:

We will begin by recalling the “down-to-earth” computation of the cohomol- ogy groups of a cyclic group with coefficients in Z from an earlier talk. Then we will show how the Lyndon / Hochschild - Serre spectral sequence can be used to obtain the known result.
Time permitting we will show how the same technique can be used to compute the cohomology groups of a dihedral group with coefficients in Z.
