In this paper, the notion of $psi -$weak contraction cite{Rhoades} isextended to fuzzy metric spaces. The existence of common fixed points fortwo mappings is established where one mapping is $psi -$weak contractionwith respect to another mapping on a fuzzy metric space. Our resultgeneralizes a result of Gregori and Sapena cite{Gregori}.

In this paper, we introduce cyclic weak φ−contractions in fuzzy metric spaces and utilize the same to prove some results on existence and uniqueness of fixed point in fuzzy metric spaces. Some related results are also proved besides furnishing illustrative examples.

We characterize the completeness of fuzzy quasi-metric spaces by means a fixed point theorem Kannan-type.Thus, we extend classical characterization metric due to Subrahmanyam as well recent resultsin literature on and completeness, respectively. Wealso introduce discuss contractions Chatterjea-type in this asymmetric context.

Abstract This paper aims to present the concept of multi-valued mappings in fuzzy cone metric spaces and prove some basic lemmas, a Hausdorff metric, fixed point results for set-valued cone-contraction mappings. We theorem rational type cone-contractions spaces. Our extend improve given literature.

Abstract We propose a method for constructing generalized fuzzy Hausdorff distance on the set of nonempty compact subsets given metric space in sence George–Veeramni and Tian–Ha–Tian. Next, we define fractal spaces. Morever, obtain fixed point theorem class contractions present an application integranl equation.
