Group Cohomology

Translations of Mathematical Monographs, 2018
Let G be a group. We can form the group ring Z[G] over G; by definition it is the set of formal finite sums ∑ aigi, where ai ∈ Z, gi ∈ G, and multiplication is defined in the obvious manner. We shall call an abelian group A a G-module if it is a left Z[G]
