Abstract |
|
Let G be a discrete group and A the L1 algebra over the field of complex numbers of G. The aim of the paper is to consider some combinatorial conditions on the group G which imply symmetry of the algebra A. One result is as follows: If a group F contains a subgroup G of finite index such that any element of G has finitely many conjugates, then the group algebra A of F is symmetric. |
