正则半群的亚左—C同余格

The Lattice of Sl-clifford Congruences on A Regular Semigroup

证明了正则半群Ｓ上全体亚左－Ｃ同余ＳＬＣ（Ｓ），组成Ｃ（Ｓ）的子格，研究了ＳＬＣ（Ｓ）的一类，给出了．一类的最大元的性质．

In this paper lattice SLC(S) of all SL- Clifford congruence on a regular semigroup S is studied. We prove that the relation restricted to SLC ( S) is a congruence, and present a characterion of the greatest element of each class.
