Khan, Safeer Hussain; Abbas, Mujahid
(SpringerOpen, 2014)
The existence of fixed points of single-valued mappings in modular function spaces
has been studied by many authors. The approximation of fixed points in such spaces
via convergence of an iterative process for single-valued ...

operations like union, intersection and difference of hypersoft sets; basic ingrediants for topological
structures on the ...

The aim of this paper is to present coincidence best proximity point results of Fg-weak contractive
mappings in partially ordered metric space. Some examples are presented to prove the validity of our
results.

Recently Abbas [M. Abbas, Coincidence points of multivalued f−almost nonexpansive mappings, Fixed
Point Theory, 13 (1) (2012), 3–10] introduced the concept of f−almost contraction which generalizes the
class of multivalued ...

Aghajani, Asadollah; Abbas, Mujahid; Roshan, Jamal Rezaei
(University of Nis, 2014)
In this work, using the concepts of G-metric and b-metric we define a new type of metric which
we call Gb-metric. We study some basic properties of such metric. We also prove a common fixed point
theorem for six mappings ...

Rahimi, Hamidreza; Abbas, Mujahid; Rad, Ghasem Soleimani
(University of Nis, Serbia, Faculty of Sciences and Mathematics, 2015)
A vector metric space is a generalization of a metric space, where the metric is Riesz space
valued. We prove some common fixed point theorems for four mappings in ordered vector metric spaces.
Obtained results extend ...

We first introduce a new concept of b-dislocated metric space as a generalization of
dislocated metric space and analyze different properties of such spaces.
A fundamental result for the convergence of sequences in ...
