Intuitionistic fuzzy {\psi}-{\phi}-contractive mappings and fixed point theorems in non-Archimedean intuitionistic fuzzy metric spaces

Abstract

In this paper intuitionistic fuzzy {\psi}-{\phi}-contractive mappings are introduced. Intuitionistic fuzzy Banach contraction theorem for M-complete non-Archimedean intuitionistic fuzzy metric spaces and intuitionistic fuzzy Elelstein contraction theorem for non-Archimedean intuitionistic fuzzy metric spaces by intuitionistic fuzzy {\psi}-{\phi}-contractive mappings are proved.
