Some fixed point theorems for G-nonexpansive mappings on ultrametric spaces and non-Archimedean normed spaces with a graph

A very interesting approach in the theory of fixed point is some general structures was recently given by Jachymski by using the context of metric spaces endowed with a graph. The purpose of this article is to present some new fixed point results for G-nonexpansive mappings defined on an ultrametric space and non-Archimedean normed space which are endowed with a graph. In particular, we investigate the relationship between weak connectivity graph and the existence of fixed point for these mappings

Common Fixed Points for Generalized φ-Pair Mappings on Cone Metric Spaces

We define the concept of generalized φ-pair mappings and prove some common fixed point theorems for this type of mappings. Our results generalize some recent results

New Results for Set-Valued Mappings on Ordered Metric Spaces

We establish some new fixed point results for order-closed multivalued mappings in complete metric spaces endowed with a partial order
