Ishikawa iteration process with errors for nonexpansive mappings in uniformly convex Banach spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 1, Page 49-53, 2000., 2000
We shall consider the behaviour of Ishikawa iteration with errors in a uniformly convex Banach space. Then we generalize the two theorems of Tan and Xu without the restrictions that C is bounded and limsupnsn < 1.

An implicit algorithm for two finite families of nonexpansive maps in hyperbolic spaces

open access: yes, 2012
In this article, we propose and analyze an implicit algorithm for two finite families of nonexpansive maps in hyperbolic spaces. Results concerning Δ-convergence as well as strong convergence of the proposed algorithm are proved.

Maia type fixed point theorems for Ćirić-Prešić operators

open access: yesActa Universitatis Sapientiae: Mathematica, 2018
The main aim of this paper is to obtain Maia type fixed point results for Ćirić-Prešić contraction condition, following Ćirić L. B. and Prešić S. B. result proved in [Ćirić L. B.; Prešić S. B.

Existence of tripled coincidence points in ordered b-metric spaces and an application to a system of integral equations

open access: yes, 2013
In this paper, tripled coincidence points of mappings satisfying some nonlinear contractive conditions in the framework of partially ordered b-metric spaces are obtained. Our results extend the results of Berinde and Borcut (Nonlinear Anal. 74:4889-4897,

A NOTE ON THE PAPER “ON COMPLETENESS IN METRIC SPACES AND FIXED POINT THEOREMS"

open access: yes, 2020
In the present note, we show that the assumption of continuity used in the fixed point theorem of Gregori et al. (Results Math. 73 (2018), no. 4, Art. 142, 13) can be relaxed to some weaker version of continuity.

Eigenvalues and ranges for perturbations of nonlinear accretive and monotone operators in Banach spaces

open access: yesAbstract and Applied Analysis, Volume 2, Issue 3-4, Page 197-205, 1997., 1997
Various eigenvalue and range results are given for perturbations of m‐accretive and maximal monotone operators. The eigenvalue results improve and extend some recent results by Guan and Kartsatos, while the range theorem gives an affirmative answer to a recent problem of Kartsatos.

On the strong convergence of a modified S-iteration process for asymptotically quasi-nonexpansive mappings in a CAT(0) space

open access: yes, 2013
In this paper, we give strong convergence theorems for the modified S-iteration process of asymptotically quasi-nonexpansive mappings on a CAT(0) space which extend and improve many results in the literature.MSC: Primary 47H09; secondary 47H10.

An extension of a best approximation theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 4, Page 711-716, 1996., 1995
In this paper an extension of a theorem of Prolla is given and several interesting corollaries are derived. Fixed point results are also given in the end.

Coupled coincidence point theorems for contractions without commutative condition in intuitionistic fuzzy normed spaces

open access: yes, 2011
Recently, Gordji et al. [Math. Comput. Model. 54, 1897-1906 (2011)] prove the coupled coincidence point theorems for nonlinear contraction mappings satisfying commutative condition in intuitionistic fuzzy normed spaces.
