Boundedness of fractional operators in weighted variable exponent spaces with non doubling measures [PDF]

open access: yes, 2009
In the context of variable exponent Lebesgue spaces equipped with a lower Ahlfors measure we obtain weighted norm inequalities over bounded domains for the centered fractional maximal function and the fractional integral ...

Boundedness for commutators of fractional integrals on Herz-Morrey spaces with variable exponent

open access: yes, 2013
In this paper, some boundedness for commutators of fractional integrals are obtained on Herz-Morrey spaces with variable exponent applying some properties of varible exponent and $\BMO$ function.Comment: In 2013, it is accepted by Kyoto Journal of ...

A mass transportation approach for Sobolev inequalities in variable exponent spaces [PDF]

open access: yes, 2015
In this paper we provide a proof of the Sobolev-Poincar\'e inequality for variable exponent spaces by means of mass transportation methods. The importance of this approach is that the method is exible enough to deal with different inequalities.

Molecular Characterizations and Dualities of Variable Exponent Hardy Spaces Associated with Operators

open access: yes, 2015
Let $L$ be a linear operator on $L^2(\mathbb R^n)$ generating an analytic semigroup $\{e^{-tL}\}_{t\ge0}$ with kernels having pointwise upper bounds and $p(\cdot):\ \mathbb R^n\to(0,1]$ be a variable exponent function satisfying the globally log-H\"older

Commutators of singular integrals on generalized $L^p$ spaces with variable exponent [PDF]

open access: yes, 2004
A classical theorem of Coifman, Rochberg, and Weiss on commutators of singular integrals is extended to the case of generalized $L^p$ spaces with variable exponent.Comment: 13 ...

Variable λ-Central Morrey Space Estimates for the Fractional Hardy Operators and Commutators

open access: yesJournal of Mathematics, 2022
This paper aims to show that the fractional Hardy operator and its adjoint operator are bounded on central Morrey space with variable exponent. Similar results for their commutators are obtained when the symbol functions belong to λ-central bounded mean ...

Parent‐to‐Child Information Disclosure in Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Ground state solution for a class of supercritical nonlocal equations with variable exponent

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper, we obtain the existence of positive critical point with least energy for a class of functionals involving nonlocal and supercritical variable exponent nonlinearities by applying the variational method and approximation techniques. We apply

Fractional integrals and hypersingular integrals in variable order Hölder spaces on homogeneous spaces

open access: yesJournal of Function Spaces and Applications, 2010
We consider non-standard Hölder spaces Hλ(⋅)(X) of functions f on a metric measure space (X, d, μ), whose Hölder exponent λ(x) is variable, depending on x ∈ X.
