摘要:

设S 是一正则半群,E(S) 为正则半群S 上的幂等元集。通过建立S 上的几种集合关系,得到了判断含零元同余自由
正则半群的新方法。

Abstract:

In this paper, let S be a regular semigroup, and E(s) be the set of idempotent of regular semigroup S. By constructing the relation between sets in S, we obtain a new method to show the regular semigroup S with zero element is a congruence-free regular semigroup.

Key words: regular semigroups, the set of idempotent element, disjunct sets, congruence-free regular semigroups
