拟-C半群的结构

摘要

In this article,we study the structure of quasi-C semigroups.By quasi-direct product,we prove that a semigroup S is quasi-C semigroup if and only if S is a quasi-direct product of a left normal band,a Clifford semigroup and a right normal band,which generalizes the Clifford semigroup.%本文研究了拟-C半群的结构.利用拟直积的方法,证明了半群S是拟-C半群,当且仅当S是左正规带,Clifford半群和右正规带的拟直积,推广了Clifford半群.
