The idempotents of a class of 0-simple inverse semigroups

Janet E. Mills

Vol. 81 (1979), No. 1, 159–166
Abstract

An ω-semigroup is a semigroup whose idempotents form an ω-chain e0 > e1 > e2 > . In this paper we characterize the semilattice of idempotents of a 0-simple inverse semigroup whose nonzero 𝒟-classes form ω-semigroups.
