Title:
Control of fusion and cohomology of trivial
source modules
Abstract:
Let $G$ be a finite group and $H$ a subgroup.
We give an algebraic proof of Mislin's theorem
which states that the restriction map from
$G$ to $H$ on mod-$p$ cohomology is an isomorphism
if and only if $H$ controls $p$-fusion in $G$.
