Abstract
The purpose of this paper is to introduce a new type of contraction called fuzzy F-contraction. As compared to the F-contraction in the existing literature, our fuzzy F-contraction is much simpler and more straightforward, since it contains only one condition—that is, the function F is strictly increasing. Moreover, some fixed-point theorems for fuzzy F-contraction are presented. Further, some examples are given to illustrate its validity and superiority. In addition, by applying a very significant lemma, we show that our proofs of most fixed-point theorems are shorter and more elegant than ones in the literature.

One of the most interesting motivations is the fixed-point theory established in fuzzy metric spaces, which was initiated by Grabiec [5], where a fuzzy metric version of the Banach contraction principle was presented
Summary
Introduction and PreliminariesBased on the theory of fuzzy sets introduced by Zadeh [1], George and Veeramani [2], provided axioms to fuzzy metric spaces. We cope with fixed-point theorems for fuzzy F-contraction in the setting of fuzzy metric spaces. Utilizing the lemma mentioned above, we obtain some fixed-point theorems for fuzzy F-contraction with shorter conditions and straightforward proofs.
