Cohomology of cyclic groups of prime square order
Cohomology of cyclic groups of prime square order
Let G be a cyclic group of order p 2 , p a prime, and let U be its unique proper subgroup.If A is any G-module, then the four cohomology groups H%G, A) HKG, A) H\U, A) H\U, A) determine all the cohomology groups of A with respect to G …
