A note on quasi R*-invariant measures on semigroups

N.A. Tserpes

Abstract

A characterization of quasi r*-invariant measures on metric topological semigroups is obtained by showing that their support has a left group structure thus generalizing previously known results for relatively r*-invariant measures and the topo-algebraic structure of their support.
