Abstract
The purpose of this paper is to prove some fixed point and common fixed point theorems for expansion maps in intuitionistic fuzzy metric spaces. The main result has been proved for two pairs of non-surjective expansion maps on noncomplete intuitionistic fuzzy metric space through weak compatibility. Our results extend, generalize and intuitionistic fuzzify several fixed point theorems on metric spaces, Menger PM-spaces and fuzzy metric spaces.
