A semilattice decomposition into semigroups having at most one idempotent

Mohan S. Putcha and Julian Weissglass

Vol. 39 (1971), No. 1, 225–228
Abstract

A semigroup S is said to be viable if ab = ba whenever ab and ba are idempotents. The main theorem of this article proves in part that S is a viable semigroup if and only if S is a semi-lattice of P-indecomposable semigroups having at most one idempotent.
