Semigroups and ��-Semigroups

This book mainly focuses on some aspects of semigroups and Γ-semigroups related with different ideals as well as their various generalizations including fuzzyfication and intuitionistic fuzzyfication. The notions of characteristic ideals fuzzy characteristic ideals generalized bi-ideals fuzzy generalized bi-ideals intuitionistic fuzzy generalized bi-ideals radicals of fuzzy ideals and fuzzy primary ideals of a Γ-semigroup have been introduced and studied. Various characterization theorems of Γ-semigroups have been obtained by using the notions of generalized bi-ideals and fuzzy generalized bi-ideals. The concepts of ideals prime ideals semiprime ideals in Γ-semigroups have been generalized in terms of Atanassov’s intuitionistic fuzzy subsets. Also the notions of intuitionistic fuzzy ideal extension in a semigroup and a Γ-semigroup have been introduced and studied them directly and via operator semigroups of a Γ-semigroup. Various characterization theorems of semigroups have also been obtained in terms of intuitionistic fuzzy magnified translation and intuitionistic fuzzy points.
