In this paper we study the closed subsemigroups of a Clifford semigroup. shown that{∪- αεY' Gα, [ Y' ε P(Y)} is the set of all closed subsemigroups of It is a Clifford semigroup S = {Y; Gα; Фα,β}, where Y'- denotes the suhsemilattice of Y generated by Y'. In particular, G is the only dosed subsemigroup of itself for a group G and each one of subsemilattiees of a semilattiee is closed. Also, it is shown that the semiring P(S) is isomorphic to the semiring P(Y) for a Clifford semigroup S = [Y; Gα; Фα,β]. 相似文献
