In this paper,we investigate another structure of left C-semigroups by means of the wreath product,and the wreath product structure of left C-semigroups is obtained.
利用半群圈积的概念得到了左C-半群的又一种结构——圈积结构。
Shum extended Clifford semigroups in the class of regular semigroups and gave the definition of left C-semigroups in 1991.
1991年，朱聘瑜，郭聿琦和岑嘉评在正则半群范围内，对Clifford半群进行了推广，定义了所谓左C-半群，不仅对左C-半群的特征进行了刻画，而且给出了左C-半群的ξ-积结构。
This paper gives a necessary and sufficient condition for the semidirect product of two semigroups which are not monoids to be a left Clifford semigroup.
给出了两个非含幺半群的半直积是左Clifford半群的充要条
