Commuting contractive idempotents in measure algebras

Functional Analysis 2016-02-17 v1

Abstract

We determine when contractive idempotents in the measure algebra of a locally compact group commute. We consider a dynamical version of the same result. We also look at some properties of groups of measures whose identity is a contactive idempotent.
