Some Properties of Regular Semigroups Possess a Medial Idempotent
Sajjad Hussain, T. Anwer, Huei-Chen Chien · 2010
In this paper we study the properties of all such semigroups particularly all regular semigroups that contains a medial idempotent z that is , an idempotent such that ¯ E is the subsemigroup of S generated by the idempotents, then for all a belongs to ¯ E a = aza which is normal.
