Reversibility and Banach Algebras
arXiv:1110.6353
Abstract
An element of a group is called {\em reversible} if it is conjugate in the group to its inverse. In this paper we review some results about the structure of groups involving the reversible elements and we pose some questions about groups associated to a Banach algebra.
The original title was 'Reversibility and Banach algebras'. It was published as 'Reversibility questions in groups arising in analysis'
