Characterizations of Quasi-Metric and G-Metric Completeness Involving W-Distances and Fixed Points
(de Gruyter Poland Sp Z O O, 2022) Romaguera, Salvador; Tirado, Pedro; Karapinar, Erdal; Karaplnar, Erdal
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-metric completeness is obtained. Our approach allows us to retrieve several key examples occurring in various fields of mathematics and computer science and that are modeled as non-T-1 quasi-metric spaces. As an application, we deduce a characterization of complete G-metric spaces in terms of a weak version of Caristi's theorem that involves a G-metric version of w-distances.

A Discussion on P-Geraghty Contraction on Mw-Quasi Spaces
(Mdpi, 2020) Fulga, Andreea; Karapinar, Erdal; Tirado, Pedro; Alegre, Carmen
In this paper we consider a kind of Geraghty contractions by using mw-distances in the setting of complete quasi-metric spaces. We provide fixed point theorems for this type of mappings and illustrate with some examples the results obtained.
