Standard Projective Simplicial Kernels and the Second Abelian Cohomology of Topological Groups

Hossein Sahleh, Hossein Esmaili Koshkoshi

Let $A$ be an abelian topological $G$-module. We give an interpretion for the second cohomology, $H^2(G,A)$, of $G$ with coefficients in $A$. As a result we show that if $P$ is a…
