Abstract

Abstract:

A good B-quasi-Ehresmann semigroup is a semigroup which has a subband B satisfying some additional conditions, in which B is called the band of projection. Orthodox semigroups, type W semigroups, orthodox supper rpp semigroups and projective orthomonoids are all good B-quasi-Ehresmann semigroups. In this paper, the characterizations of good B-quasi-Ehresmann semigroups with left semiregular bands of projections are exhibited.

Key words: B-quasi-Ehresmann semigroup, left semiregular band, B-Ehresmann semigroup, left regular band, regular band
