Abstract
In this paper, the concept of fuzzy b-open (fuzzy b-closed) sets to introduce some new types of intuitionistic fuzzy b separation axioms, intuitionistic fuzzy b-T-i space (for i = 3,4) and intuitionistic fuzzy b-regular and b-normal spaces are introduced, some theorems about them are investigated. Stronger forms of intuitionistic fuzzy b-regular and intuitionistic fuzzy b-normal spaces are introduced. Moreover, the relationships between these separation axioms and others are investigated.
