Abstract :We consider the structure of the semigroup of self-mappings of a semigroup S under pointwise composition, generated by the endomorphisms of S. We show that if S is a Clifford semigroup, with underlying semilattice Λ, then the endomorphisms of S generate a Clifford semigroup E+insert ignore into journalissuearticles values(S); whose underlying semilattice is the set of endomorphisms of Λ. These results contribute to the wider theory of seminear-rings of endomorphisms, since E+insert ignore into journalissuearticles values(S); has a natural structure as a distributively generated seminear-ring.Keywords : endomorphism, Clifford semigroup, seminear ring
