“…The structure of the semilattice of idempotents of a permutable inverse semigroup of finite length with zero is clarified in [14]. By using this result, one can readily show that each nonzero idempotent of the semigroup S is a union of atoms in the semilattice E ( S ).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
