| Abstract: |
|---|
| For any positive integer $n$,$mathcal{A}_n$ is the class of all groups $G$ such that, for $0leq i leq n$, $H^i(hat{G},A)cong H^i(G,A)$ for every finite discrete $hat{G}$-module $A$. We describe certain types of free products with amalgam and HNN extensions that are in some of the classes $mathcal{A}_n$. In addition, we investigate the residually finite groups in the class $mathcal{A}_2$. |
