Probabilistic Generalized Metric Spaces and Nonlinear Contractions

open access: yesDemonstratio Mathematica, 2016
We give a probabilistic generalization of the theory of generalized metric spaces [2]. Then, we prove a fixed point theorem for a self-mapping of a probabilistic generalized metric space, satisfying the very general nonlinear contraction condition ...

Probabilistic modular metric spaces [PDF]

open access: yesJournal of Hyperstructures, 2020
The purpose of this study is to investigate the connection between probabilistic and modular metric spaces. We discussseveral important properties such as convergence and completeness,etc, and the relationship among the mentioned properties in the ...

Statistical convergence in probabilistic generalized metric spaces w.r.t. strong topology

open access: yesJournal of Inequalities and Applications, 2021
In this paper, the concept of probabilistic g-metric space with degree l, which is a generalization of probabilistic G-metric space, is introduced. Then, by endowing strong topology, the definition of l-dimensional asymptotic density of a subset A of N l

Four Types of Fixed-Point Theorems for Multifunctions in Probabilistic Metric Spaces

open access: yesMathematics, 2021
An overview of fixed-point theorems (F.P.T.s) for multifunctions in probabilistic metric spaces is given. Extensions of the fixed-point theorems on probabilistic metric spaces of Nadler, Hadžić, Itoh, and Miheţ are presented. In the end, some hints about

Quantale-valued Cauchy tower spaces and completeness

open access: yesApplied General Topology, 2021
Generalizing the concept of a probabilistic Cauchy space, we introduce quantale-valued Cauchy tower spaces. These spaces encompass quantale-valued metric spaces, quantale-valued uniform (convergence) tower spaces and quantale-valued convergence tower ...

Probabilistic approach spaces [PDF]

open access: yesMathematica Bohemica, 2017
We study a probabilistic generalization of Lowen's approach spaces. Such a probabilistic approach space is defined in terms of a probabilistic distance which assigns to a point and a subset a distance distribution function.

On a probabilistic version of Meir-Keeler type fixed point theorem for a family of discontinuous operators

open access: yesApplied General Topology, 2021
A Meir-Keeler type fixed point theorem for a family of mappings is proved in Menger probabilistic metric space (Menger PM-space). We establish that completeness of the space is equivalent to fixed point property for a larger class of mappings that ...

Fixed point theorem by using ψ–contraction and (ϕ,φ)–contraction in probabilistic 2–metric spaces

open access: yesAlexandria Engineering Journal, 2020
This research paper investigates and proves some theorems of the fixed point for self–mapping [T:X→X] under (ϕ,ψ)–contractive mappings and (ϕ,φ)–contractive mappings in Menger probabilistic 2–metric space.

The syntactic side of autonomous categories enriched over generalised metric spaces [PDF]

open access: yesLogical Methods in Computer Science, 2023
Programs with a continuous state space or that interact with physical processes often require notions of equivalence going beyond the standard binary setting in which equivalence either holds or does not hold.

New dynamic fixed point results in Menger spaces [PDF]

open access: yesSurveys in Mathematics and its Applications, 2023
The objective of this paper is to generalize and improve some results in fixed point theorems in both complete metric space and Menger space. These results are generalizations of the analogous ones recently proved by Khojasteh [5], Demma [1], Yildirim ...
