Boundedness of Hardy‐Type Operators on Grand Weighted Herz–Morrey Spaces

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this paper, we establish the boundedness of the higher‐dimensional Hardy operator and its adjoint operator on grand weighted Herz–Morrey spaces. As corollaries, we also obtain their boundedness on grand weighted Herz spaces.

Boundedness of Singular Integral Operator in Variable Exponent Lebesgue Spaces

Mathematics
This manuscript establishes the boundedness results for a class of singular integral operators to a more general framework by imposing conditions on the Hardy–Littlewood maximal function. We establish the results where we construct a suitable range space

Hardy-littlewood maximal operators in Sobolev spaces

, 2020
Bu tezin amacı Sobolev uzaylarında maksimal operatörlerin özelliklerini incelemektir. Birinci bölümde, önce Sobolev uzayının ve maksimal fonksiyonun öneminden söz ediyoruz. Sonra dikkatimizi maksimal operatörün Sobolev uzayındaki sınırlılığına veriyoruz.

Bessel–Riesz Operator in Variable Lebesgue Spaces L^p(·)(${\mathbb{R}}_{+}$)

Axioms
This paper investigates the Bessel–Riesz operator within the framework of variable Lebesgue spaces. We extend existing results by establishing boundedness under more general conditions.

Fréchet Envelopes of Nonlocally Convex Variable Exponent Hörmander Spaces

Abstract and Applied Analysis, 2016
We show that the dual Bp·locΩ′ of the variable exponent Hörmander space Bp(·)loc(Ω) is isomorphic to the Hörmander space B∞c(Ω) (when the exponent p(·) satisfies the conditions ...

Maximal operator in variable exponent Morrey spaces

, 2008
The boundedness of the Hardy-Littlewood maximal operator on the variable Morrey spaces defined over a bounded open set in R^n is proved, under the assumption of the local Holder continuity of the exponent, completing the result obtained by L.

On the sharpness of some quantitative Muckenhoupt–Wheeden inequalities

Comptes Rendus. Mathématique
In the recent work [Cruz-Uribe et al. (2021)] it was obtained that \[ |\lbrace x\in {\mathbb{R}^d}:w(x)|G(fw^{-1})(x)|>\alpha \rbrace |\lesssim \frac{[w]_{A_1}^2}{\alpha }\int _{{\mathbb{R}^d}}|f|\,\mathrm{d} x \] both in the matrix and scalar settings ...
