Complex group algebras of finite groups: Brauer's
Problem 1
Alexander Moretó
Abstract.
Brauer's Problem 1 asks the following: what are
the possible complex group algebras of finite groups? It seems
that with the present knowledge of representation theory it is not
possible to settle this question. The goal of this paper is to
announce a partial solution to this problem. We conjecture that if
the complex group algebra of a finite group does not have more
than a fixed number $m$ of isomorphic summands, then its dimension
is bounded in terms of $m$. We prove that this is true for every
finite group if it is true for the symmetric groups.
