  In this paper some fundamental relationships of a gamma semigroup and its
operator semigroups in terms of intuitionistic fuzzy subsets, intuitionistic
fuzzy ideals, intuitionistic fuzzy prime(semiprime) ideals, intuitionistic
fuzzy ideal extensions are obtained. These are then used to obtain some
important characterization theorems of gamma semigroups in terms of
intuitionistic fuzzy subsets so as to highlight the role of operator semigroups
in the study of gamma semigroups in terms of intuitionistic fuzzy subsets.
