Regular semigroups

Semigroup Forum

A pair (S, P) of a regular semigroups S and a subset P of Es where Es is the set of all idempotent elements of S is called a P-regular semigroup S(P) if it satisfies the following: (1) P2 ⊆ES (2) qPq⊆P for all q∈P (3) for any x∈S there exists x†∈V(x) (the set of inverses of x), such that xP1 x†⊆P and x† P1 x⊆P where P1=P∩{1}. The class of orthodox semigroups and the class of regular *-semigroups are within the class of P-regular semigroups. This paper gives a characterisation of the P-kernel of a P-congruence. © 1992 Springer-Verlag New York Inc.
