Convexity and boundedness relaxation for fixed point theorems in modular spaces

open access: yesApplied General Topology, 2021
Although fixed point theorems in modular spaces have remarkably applied to a wide variety of mathematical problems, these theorems strongly depend on some assumptions which often do not hold in practice or can lead to their reformulations as particular ...

Implicit Contractive Mappings in Modular Metric and Fuzzy Metric Spaces

open access: yesThe Scientific World Journal, 2014
The notion of modular metric spaces being a natural generalization of classical modulars over linear spaces like Lebesgue, Orlicz, Musielak-Orlicz, Lorentz, Orlicz-Lorentz, and Calderon-Lozanovskii spaces was recently introduced.

Some fixed-point theorems for a general class of mappings in modular G-metric spaces [PDF]

open access: yesArab Journal of Mathematical Sciences, 2022
Purpose – This paper aims to prove some fixed-point theorems for a general class of mappings in modular G-metric spaces. The results of this paper generalize and extend several known results to modular G-metric spaces, including the results of Mutlu et ...

On the Lebesgue and Sobolev spaces on a time-scale [PDF]

open access: yesOpuscula Mathematica, 2019
We consider the generalized Lebesgue and Sobolev spaces on a bounded time-scale. We study the standard properties of these spaces and compare them to the classical known results for the Lebesgue and Sobolev spaces on a bounded interval.

Some Results on Normalized Duality Mappings and Approximating Fixed Points in Convex Real Modular Spaces

open access: yesمجلة بغداد للعلوم, 2021
In this paper, the concept of normalized duality mapping has introduced in real convex modular spaces. Then, some of its properties have shown which allow dealing with results related to the concept of uniformly smooth convex real modular spaces.

One-Local Retract and Common Fixed Point in Modular Metric Spaces

open access: yesAbstract and Applied Analysis, 2013
The notion of a modular metric on an arbitrary set and the corresponding modular spaces, generalizing classical modulars over linear spaces like Orlicz spaces, were recently introduced.

A characterization of convex φ-functions [PDF]

open access: yesOpuscula Mathematica, 2012
The properties of four elements \((LPFE)\) and \((UPFE)\), introduced by Isac and Persson, have been recently examined in Hilbert spaces, \(L^p\)-spaces and modular spaces. In this paper we prove a new theorem showing that a modular of form \(\rho_{\Phi}(

Fixed point theorems in modular G-metric spaces

open access: yesJournal of Inequalities and Applications, 2021
We prove the existence and uniqueness of fixed points of some generalized contractible operators defined on modular G-metric spaces and also prove the modular G-continuity of such operators.

Property P in modular metric spaces

open access: yesVojnotehnički Glasnik, 2022
Introduction/purpose: The aim of this paper is to present the concept of the generalized ∅−weak contractive condition involving various combinations of d(x,y) in modular metric spaces. Methods: Conventional theoretical methods of functional analysis.

Monotonicity in Modular Function Spaces Equipped with O-norm

open access: yesJournal of Harbin University of Science and Technology
Modular function spaces are extensions of Lebesgue spaces and Orlicz spaces. We introduce Orlicz norm in Modular function spaces, and study the monotonicity in modular function spaces equipped with O-norm and L-norm.
