Statistical Convergence of Double Sequences on Probabilistic Normed Spaces [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
The concept of statistical convergence was presented by Steinhaus in 1951. This concept was extended to the double sequences by Mursaleen and Edely in 2003.

Fixed Points and Stability for Functional Equations in Probabilistic Metric and Random Normed Spaces [PDF]

open access: yesFixed Point Theory and Applications, 2009
We prove a general Ulam-Hyers stability theorem for a nonlinear equation in probabilistic metric spaces, which is then used to obtain stability properties for different kinds of functional equations (linear functional equations, generalized equation of ...

Some new lacunary statistical convergence with ideals [PDF]

open access: yesJournal of Inequalities and Applications, 2017
In this paper, the idea of lacunary I λ $I_{\lambda}$ -statistical convergent sequence spaces is discussed which is defined by a Musielak-Orlicz function.

Menger probabilistic normed space is a category topological vector space [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2016
In this paper, we formalize the Menger probabilistic normed space as a category in which its objects are the Menger probabilistic normed spaces and its morphisms are fuzzy continuous operators.

On the existence and uniqueness problems of solutions for set-valued and single-valued nonlinear operator equations in probabilistic normed spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this paper, we introduce the concept of more general probabilistic contractors in probabilistic normed spaces and show the existence and uniqueness of solutions for set-valued and single-valued nonlinear operator equations in Menger probabilistic ...

A General System of Euler–Lagrange-Type Quadratic Functional Equations in Menger Probabilistic Non-Archimedean 2-Normed Spaces [PDF]

open access: yesAbstract and Applied Analysis, 2011
We prove the generalized Hyers-Ulam-Rassias stability of a general system of Euler-Lagrange-type quadratic functional equations in non-Archimedean 2-normed spaces and Menger probabilistic non-Archimedean-normed spaces.

Fixed point theorems in generating spaces of quasi-norm family and applications

open access: yesFixed Point Theory and Applications, 2006
Some new concepts of generating spaces of quasi-norm family are introduced and their linear topological structures are studied. These spaces are not necessarily locally convex.

Conceptual interpretation of interval valued 𝑇̅- normed fuzzy 𝛽-subalgebra [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
Triangular norm is a sort of binary operation often used in the fields such as fuzzy logic, probabilistic metric spaces and so on. In this paper, the concept of interval valued 𝑇̅-normed fuzzy 𝛽-subalgebra is proposed and its associated outcomes ...

On best proximity point theorems for relatively nonexpansive mappings in locally convex spaces

open access: yesMoroccan Journal of Pure and Applied Analysis, 2023
This paper explores the concept of normal structure by introducing a generalized form known as P-proximal normal structure. Focusing on the framework of Hausdorff locally convex spaces, the study establishes optimal proximity outcomes for both cyclic and
