The Maximum Idempotent Separating Congruence on E-inversive E-semigroups
Manoj Siripitukdet, Supavinee Sattayaporn · 2008
A semigroup S is an E-inversive E-semigroup if for every a ∈ S, there exists an element x ∈ S such that ax is idempotent and the set of all idempotents of S forms a subsemigroup. The aim of this paper is to investigate the maximum idempotent separating congruence on E-inversive E-semigroups by using a full and weakly self-conjugate subsemigroup.
