Quadruple fixed point result in m-metric space

open access: yes, 2021
The Banach Contraction theorem is the basis of the theory of fixed points. Many scholars have been working in different directions on the Banach Theorem. Further theorems on coupled, tripled and quadruple fixed points are established.

Iterated function systems consisting of F-contractions

open access: yesFixed Point Theory and Applications, 2013
In this paper we consider a particular case of a contractive self-mapping on a complete metric space, namely the F-contraction introduced by Wardowski (Fixed Point Theory Appl.

A weak ergodic theorem for infinite products of Lipschitzian mappings

open access: yesAbstract and Applied Analysis, Volume 2003, Issue 2, Page 67-74, 2003., 2003
Let K be a bounded, closed, and convex subset of a Banach space. For a Lipschitzian self‐mapping A of K, we denote by Lip(A) its Lipschitz constant. In this paper, we establish a convergence property of infinite products of Lipschitzian self‐mappings of K.

A Universal Separable Diversity

open access: yesAnalysis and Geometry in Metric Spaces, 2017
The Urysohn space is a separable complete metric space with two fundamental properties: (a) universality: every separable metric space can be isometrically embedded in it; (b) ultrahomogeneity: every finite isometry between two finite subspaces can be ...

Intermediate Value Property for the Assouad Dimension of Measures

open access: yesAnalysis and Geometry in Metric Spaces, 2020
Hare, Mendivil, and Zuberman have recently shown that if X ⊂ ℝ is compact and of non-zero Assouad dimension dimA X, then for all s > dimA X, X supports measures with Assouad dimension s. We generalize this result to arbitrary complete metric spaces.

Weakly compactly generated Frechet spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2, Issue 4, Page 721-724, 1979., 1979
It is proved that a weakly compact generated Frechet space is Lindelöf in the weak topology. As a corollary it is proved that for a finite measure space every weakly measurable function into a weakly compactly generated Frechet space is weakly equivalent to a strongly measurable function.

Common fixed point theorem of six self-mappings in Menger spaces using (CLRST) property

open access: yesOpen Mathematics, 2018
In this paper, we study the existence and uniqueness of common fixed point of six self-mappings in Menger spaces by using the common limit range property (denoted by (CLRST)) of two pairs.

Common fixed points of almost generalized (ψ,φ)s-contractive mappings in ordered b-metric spaces

open access: yes, 2013
In this paper, we introduce the notion of almost generalized (ψ,φ)s-contractive mappings and we establish some fixed and common fixed point results for this class of mappings in ordered complete b-metric spaces.

On statistical convergence in quasi-metric spaces

open access: yesDemonstratio Mathematica, 2019
A quasi-metric is a distance function which satisfies the triangle inequality but is not symmetric in general. Quasi-metrics are a subject of comprehensive investigation both in pure and applied mathematics in areas such as in functional analysis ...

Common fixed points for single-valued and multi-valued maps satisfying a generalized contraction in G-metric spaces

open access: yes, 2012
In this article, we establish some common fixed point theorems for a hybrid pair {g, T} of single valued and multi-valued maps satisfying a generalized contractive condition defined on G-metric spaces. Our results unify, generalize and complement various
