研究群的所有右陪集构成的集合,证明它在给定的乘法下是逆半群,并研究它的幂等元性质;同时给出它为C lifford半群的充要条件。
In this paper,we discuss the set of all cosets of a group.It is shown that the set is an inverse semigroup under a given multiplication and research the properties of its idempotents.Moreover,a necessary and sufference condition for it to be a Clifford semigroup are given.
