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,

Approximation of the common minimum-norm fixed point of a finite family of asymptotically nonexpansive mappings

open access: yes, 2013
We introduce an iterative process which converges strongly to the common minimum-norm fixed point of a finite family of asymptotically nonexpansive mappings.

Meir-Keeler ɑ-contractive fixed and common fixed point theorems

open access: yes, 2013
Generalized Meir-Keeler α-contractive functions and pairs are introduced and their fixed and common fixed point theorems are obtained. Also, the so-called generalized Meir-Keeler α-f-contractive maps commuting with f are introduced and their coincidence ...

Stability of additivity and fixed point methods

open access: yes, 2013
We show that the fixed point methods allow to investigate Ulam’s type stability of additivity quite efficiently and precisely. Using them we generalize, extend and complement some earlier classical results concerning the stability of the additive Cauchy ...
