摘要:

良B-拟-Ehresmann半群是幂等元子带B满足一些条件的半群,其中B被称为投射带。 纯整半群、型W半群、纯整超rpp半群和投射纯整幺半群都是良B-拟-Ehresmann半群。本文刻画了投射带是左半正则带的良B-拟-Ehresmann半群。

关键词: B-拟-Ehresmann半群, B-Ehresmann半群, 左正则带, 左半正则带, 正则带

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
