Convergence theorems for a family of multivalued nonexpansive mappings in hyperbolic spaces

open access: yesOpen Mathematics, 2016
In this article we modify an iteration process to prove strong convergence and Δ— convergence theorems for a finite family of nonexpansive multivalued mappings in hyperbolic spaces.

Fixed point theorem for generalized weak contractions satisfying rational expressions in ordered metric spaces

open access: yesFixed Point Theory and Applications, 2011
In this paper, we prove a fixed point theorem for generalized weak contractions satisfying rational expressions in partially ordered metric spaces. The result is a generalization of a recent result of Harjani et al. (Abstr. Appl.

Convergence and stability of generalized φ-weak contraction mapping in CAT(0) spaces

open access: yesOpen Mathematics, 2017
The aim of this paper is to prove some fixed point results for generalized φ-weak contraction mapping and study a new concept of stability which is called comparably almost T-stable by using iterative schemes in CAT(0) spaces.

Some new fixed point results in b-metric spaces

open access: yesTopological Algebra and its Applications, 2018
In this paper, we consider, discuss, improve and generalize recent fixed point results for mappings in b-metric space. These results are generalizations of the analogous ones recently proved by Khojasteh et al. [12] and Demma et al. [8].

Some fixed point results on ultrametric spaces endowed with a graph

open access: yesDemonstratio Mathematica
The present article deals with new fixed point theorems by means of GG-strongly contractive maps. The research findings are demonstrated in a spherically complete ultrametric space with a graph for single-valued mappings. The special cases of the results

Fixed point results for generalized convex orbital Lipschitz operators

open access: yesDemonstratio Mathematica
Krasnoselskii’s iteration is a classical and important method for approximating the fixed point of an operator that satisfies certain conditions. Many authors have used this approach to obtain several famous fixed point theorems for different types of ...
