On Contractions Via Simulation Functions On Extended B-Metric Spaces
(Univ Miskolc inst Math, 2020) Karapinar, Erdal; Chifu, Cristian
In this paper, we introduce the notion of an admissible extended Z-contraction mapping in the setting of extended b-metric spaces. As an application, we consider Ulam stability problems based on our contractions. The presented results cover several existing results in the literature.

Results in Wt-Distance Over B-Metric Spaces
(Mdpi, 2020) Chifu, Cristian; Karapinar, Erdal
In this manuscript, we introduce Meir-Keeler type contractions and Geraghty type contractions in the setting of the wt-distances over b-metric spaces. We examine the existence of a fixed point for such mappings. Under some additional assumption, we proved the uniqueness of the found fixed point.
