Abstract
In this paper we study the closed subsemigroups of a Clifford semigroup.
It is shown that {∪α∈¯Y′Gα|Y′∈P(Y)} is the set of all closed subsemigroups of
a Clifford semigroup S=[Y;Gα;ϕα,β], where ¯Y′ denotes the subsemilattice of Y generated by Y′. In particular, G is the only closed subsemigroup of itself for a
group G and each one of subsemilattices of a semilattice 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;ϕα,β].
