Abstract
In intuitionistic fuzzy metric spaces, under various compatible mapping conditions, we propose a common fixed point theorem for four mappings and generalize it to a common fixed point theorem for four finite families of mappings. On the basis of that, we can further extend theorems to the common fixed point theorems of six finite families of mappings.
