Local Muckenhoupt class for variable exponents

Journal of Inequalities and Applications, 2021
This work extends the theory of Rychkov, who developed the theory of A p loc $A_{p}^{\mathrm{loc}}$ weights. It also extends the work by Cruz-Uribe SFO, Fiorenza, and Neugebauer. The class A p ( ⋅ ) loc $A_{p(\cdot )}^{\mathrm{loc}}$ is defined.

Norms of some operators between weighted-type spaces and weighted Lebesgue spaces

AIMS Mathematics, 2023
<abstract><p>We calculate the norms of several concrete operators, mostly of some integral-type ones between weighted-type spaces of continuous functions on several domains. We also calculate the norm of an integral-type operator on some subspaces of the weighted Lebesgue spaces.</p></abstract>

Two-weight inequalities for singular integral operators satisfying a variant of Hörmander's condition

Journal of Function Spaces and Applications, 2009
In this paper, we present some sufficient conditions for the boundedness of convolution operators that their kernel satisfies a certain version of Hörmander's condition, in the weighted Lebesgue spaces Lp,ω (ℝn).

Approximation on parametric extension of Baskakov–Durrmeyer operators on weighted spaces

Journal of Inequalities and Applications, 2019
In the present manuscript, we define a non-negative parametric variant of Baskakov–Durrmeyer operators to study the convergence of Lebesgue measurable functions and introduce these as α-Baskakov–Durrmeyer operators.

Boundedness of Multidimensional Dunkl-Hausdorff Operators

Journal of Function Spaces, 2020
In the present paper, we introduce the multidimensional Dunkl-Hausdorff operator ℋκ and we give simple sufficient conditions so that these operators be bounded on the weighted lebesgue spaces Lκpℝn and in the Hardy space Hκ1ℝn associated with the Dunkl ...

Generalization of one theorem of F. Riesz to some other spaces

Қарағанды университетінің хабаршысы. Математика сериясы, 2020
It is known from the analysis course that in order a function to serve as an undefined integral of a summable function, it is necessary and sufficient that it be absolutely continuous. Therefore, it is natural to raise the question of the characteristic

Weighted norm inequalities for convolution and Riesz potential

, 2013
In this paper, we prove analogues of O'Neil's inequalities for the convolution in the weighted Lebesgue spaces.
