Involutions on the second duals of group algebras versus subamenable groups
by
Ajit Iqbal Singh
Let $L^1 (G)^{\ast \ast}$ be the second dual of the group algebra
$L^1(G)$ of a locally
compact group $G$. We study the question of involutions on $L^1
(G)^{\ast \ast}$.
A new class of subamenable groups is introduced which is universal for
all groups. There
is no involution on $L^1(G)^{\ast \ast}$ for a subamenable group
$G$.
