Regularity of Po--semigroups in Terms of Fuzzy Subsemigroups and Fuzzy Bi-ideals
Abstract
AbstractIn this paper, the notions of fuzzy subsemigroups and fuzzy bi-ideals of a po--semigroup are introduced with some of their important properties investigated. We obtain some characterizations of regular, intra-regular po--semigroups in terms of fuzzy bi-ideals. We also give a pointwise characterization of fuzzy regular subsemigroups in a po--semigroup.
