In an outstanding article published in 2008, Suzuki obtained a nice generalization of the
Banach contraction principle, from which a characterization of metric completeness was …

Involving w-distances we prove a fixed point theorem of Caristi-type in the realm of (non-
necessarily T 1) quasi-metric spaces. With the help of this result, a characterization of quasi …

The notion of wt-distance, introduced by Hussain et al. provides a natural generalization to
the b-metric framework of the well-known and fruitful concept of w-distance, initiated by Kada …

In this paper, we introduce new types of χ, F-contraction mappings by involving rational
expressions and establish two new fixed point theorems for this class of mappings in the …

[EN] In this present paper, besides other things, we introduce the concept of Ćirić-
generalized contractions via wt− distance and then we will prove some new fixed point …

In this paper, among other things, we give the idea of Ciric-contractions type via wt-distance
and then we will show some additional fixed point results for these mappings, which …
