Morita Equivalence for Semigroups

S. Talwar

(Received 5 May 1992; revised 16 June 1993)

Abstract

In this paper we shall extend the classical theory of Morita equivalence to semigroups with local units. We shall use the concept of a Morita context to rediscover the Rees theorem and to characterise completely 0-simple and regular bisimple semigroups.
