Approximate fixed points and fixed points for multi-valued almost E-contractions

Topological Algebra and its Applications, 2021
In this paper, we introduce the concept of multi-valued almost E-contractions. We then present some approximate fixed point and fixed point results for such mappings in metric spaces.

Some fixed point theorems concerning F-contraction in complete metric spaces

, 2014
In this paper, we extend the result of Wardowski (Fixed Point Theory Appl. 2012:94, 2012) by applying some weaker conditions on the self map of a complete metric space and on the mapping F, concerning the contractions defined by Wardowski.

On α-ψ-Meir-Keeler contractive mappings

, 2013
In this paper, we introduce the notion of α-ψ-Meir-Keeler contractive mappings via a triangular α-admissible mapping. We discuss the existence and uniqueness of a fixed point of such a mapping in the setting of complete metric spaces.

Coupled fixed point theorems in complete metric spaces endowed with a directed graph and application

Open Mathematics, 2017
The purpose of this paper is to present some existence results for coupled fixed point of a (φ,ψ) —contractive condition for mixed monotone operators in metric spaces endowed with a directed graph.

Common Fixed Point Theorems in Fuzzy Metric Spaces

, 2016
In this paper we used the concept of compatible of type (P) in fuzzy metric spaces. Our result generalize earlier results due to Vasuki [18], Chugh and Kumar [3] and others. 2000 Mathematics Subject Classification: 54H25, 47H10.

On some fixed point results for (s, p, α)-contractive mappings in b-metric-like spaces and applications to integral equations

Open Mathematics, 2018
In this work, we introduce the notions of (s, p, α)-quasi-contractions and (s, p)-weak contractions and deduce some fixed point results concerning such contractions, in the setting of b-metric-like spaces.

On some results on interpolative Kannan-type and CRR-type contractions.

Moroccan Journal of Pure and Applied Analysis, 2022
Recently, Karapinar, Aydi and De Hierro introduced the notions of interpolative Kannan-type contractions and interpolative CRR-type contractions and proved that they possess a fixed point when the space is complete.

Modified α-ψ-contractive mappings with applications

, 2013
The aim of this work is to modify the notions of α-admissible and α-ψ-contractive mappings and establish new fixed point theorems for such mappings in complete metric spaces. Presented theorems provide main results of Karapinar and Samet (Abstr.

Fixed Point Results for Cyclic Generalized ψ‐Weak Contraction Mapping in Rectangular b‐Metric Spaces With Applications

Abstract and Applied Analysis, Volume 2025, Issue 1, 2025.
The objective of this paper is to present a new fixed‐point result for a class of mappings named a cyclic generalized ψ‐weak contraction. We also presented the best proximity point for the contraction when the considered sets have no common points. We go through rigorous steps to prove the existence of a unique fixed‐point and best proximity point ...
