Abstract

In this paper we establish two common fixed point theorems in fuzzy metric spaces. These theorems are generalisations of the Banach contraction mapping principle and the Kannan's fixed point theorem respectively in fuzzy metric spaces. Our result is also supported by examples.

Keywords: Hadzic type t-norm, fuzzy metric space, Cauchy sequence, $\Psi$-function, weakly compatible mappings, contraction principle, Kannan type mapping, coincidence point, fixed point
