Volume 35 • Number 4 • 2012   • On Intuitionistic Fuzzy Prime Bi-Ideals of Semigroups Muhammad Shabir, Muhammad Shoaib Arif, Asghar Khan and Muhammad Aslam Abstract. In this paper, we introduce the notions of intuitionistic fuzzy prime (resp. strongly prime and semiprime) bi-ideals of a semigroup. By using these ideas we characterize those semigroups for which each intuitionistic fuzzy bi-ideal is semiprime and strongly prime. 2010 Mathematics Subject Classification: 20M10, 20M12, 08A72, 03B52.
