Intuitionistic irreducible and strongly irreducible fuzzybi-ideals of -semigroup

ABSTRACT:In this paper, we define prime, strongly prime and semiprime intuitionistic fuzzy bi-ideals of ?-semigroups, which is a generalization of the concept of prime, strongly prime and semiprime fuzzy bi-ideals of ?-semigroups. We also define irreducible and strongly irreducible intuitionistic fuzzy bi-ideals of ?-semigroups. Also, we study some of their basic properties.
