“The Lyndon-Hochschild-Serre spectral sequence”

by

Ergün Yalçın

Abstract:
Let
G be a group and H be a normal subgroup of G. Then there is a spectral
sequence, called LHS-spectral sequence, which converges to the cohomology of G and  whose
E_2 term can be expressed in terms of cohomology of H
and G/H. I will show how the HLS-spectral sequence  can
be constructed as a spectral sequence of a double  complex and then I will
illustrate its usage by doing some group cohomology
calculations using it.
