Properties of multiplication operators on the space of functions of bounded φ-variation

open access: yesOpen Mathematics, 2021
In this paper, the functions u∈BVφ[0,1]u\in B{V}_{\varphi }\left[0,1] which define compact and Fredholm multiplication operators Mu{M}_{u} acting on the space of functions of bounded φ\varphi -variation are studied.

Regular Banach space net and abstract-valued Orlicz space of range-varying type

open access: yesOpen Mathematics, 2019
This paper investigates the abstract-valued Orlicz space of range-varying type. We firstly give the notions and examples of partially continuous modular net and regular Banach space net of type (II), then deal with the definitions, constructions, and ...

Dimension Distortion by Sobolev Mappings in Foliated Metric Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2013
We quantify the extent to which a supercritical Sobolev mapping can increase the dimension of subsets of its domain, in the setting of metric measure spaces supporting a Poincaré inequality. We show that the set of mappings that distort the dimensions of

Abstract-valued Orlicz spaces of range-varying type

open access: yesOpen Mathematics, 2018
This paper mainly deals with the abstract-valued Orlicz spaces of range-varying type. Using notions of Banach space net and continuous modular net etc., we give definitions of Lϱθ(⋅)(I, Xθ(⋅)) and L+ϱθ(⋅)$\begin{array}{} L_{+}^{\varrho_{\theta(\cdot)}} \

Boundedness of vector-valued B-singular integral operators in Lebesgue spaces

open access: yesOpen Mathematics, 2017
We study the vector-valued B-singular integral operators associated with the Laplace-Bessel differential operator △B=∑k=1n−1∂2∂xk2+(∂2∂xn2+2vxn∂∂xn),v>0. $$\triangle_{B}=\sum\limits_{k=1}^{n-1}\frac{\partial^{2}}{\partial x_{k}^{2}}+(\frac{\partial^{2}}{\

A note on bi-contractive projections on spaces of vector valued continuous functions

open access: yesConcrete Operators, 2018
This paper concerns the analysis of the structure of bi-contractive projections on spaces of vector valued continuous functions and presents results that extend the characterization of bi-contractive projections given by the first author.

Multiplication operators on the space of functions of bounded variation

open access: yesDemonstratio Mathematica, 2017
In this paper,we study the properties of the multiplication operator acting on the bounded variation space BV[0, 1]. In particular,we show the existence of non-null compact multiplication operators on BV[0, 1] and non-invertible Fredholm multiplication ...

A Riesz representation theory for completely regular Hausdorff spaces and its applications

open access: yesOpen Mathematics, 2016
Let X be a completely regular Hausdorff space, E and F be Banach spaces. Let Cb(X, E) be the space of all E-valued bounded, continuous functions on X, equipped with the strict topology β.

Continuous linear operators on Orlicz-Bochner spaces

open access: yesOpen Mathematics, 2019
Let (Ω, Σ, μ) be a complete σ-finite measure space, φ a Young function and X and Y be Banach spaces. Let Lφ(X) denote the corresponding Orlicz-Bochner space and Tφ∧$\begin{array}{} \displaystyle \mathcal T^\wedge_\varphi \end{array}$ denote the finest ...

Some inequalities and superposition operator in the space of regulated functions

open access: yesAdvances in Nonlinear Analysis, 2019
Some inequalities connected to measures of noncompactness in the space of regulated function R(J, E) were proved in the paper. The inequalities are analogous of well known estimations for Hausdorff measure and the space of continuous functions.
