Necessary and Sufficient Conditions for the Boundedness of Multiple Integral Operators with Super-Homogeneous Kernels in Weighted Lebesgue Space

Axioms
Super-homogeneous functions including homogeneous functions, quasi-homogeneous functions, and several non-homogeneous functions are considered. Using the weight function method, the construction conditions of Hilbert-type multiple integral inequalities ...

On conditions for the weighted integrability of the sum of the series with monotonic coefficients with respect to the multiplicative systems

Қарағанды университетінің хабаршысы. Математика сериясы
In this paper, we studied the issues of integrability with the weight of the sum of series with respect to multiplicative systems, provided that the coefficients of the series are monotonic.

Approximation properties of a modified Gauss–Weierstrass singular integral in a weighted space

Journal of Inequalities and Applications
Singular integral operators play an important role in approximation theory and harmonic analysis. In this paper, we consider a weighted Lebesgue space L p , w $L^{p,w}$ , define a modified Gauss–Weierstrass singular integral on it, and study direct and ...

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

Szász–Beta Operators Linking Frobenius–Euler–Simsek-Type Polynomials

Axioms
This manuscript associates with a study of Frobenius–Euler–Simsek-type Polynomials. In this research work, we construct a new sequence of Szász–Beta type operators via Frobenius–Euler–Simsek-type Polynomials to discuss approximation properties for the ...

The Sneddon ℛ-Transform and Its Inverse over Lebesgue Spaces

Axioms
We study the Sneddon R-transform and its inverse in the setting of Lebesgue spaces. Generated by the mixed trigonometric kernel xcos(xt)+hsin(xt), the R-transform acts as a unifying operator for sine- and cosine-type integral transforms.

Bounds of Different Integral Operators in Tensorial Hilbert and Variable Exponent Function Spaces

Mathematics
In dynamical systems, Hilbert spaces provide a useful framework for analyzing and solving problems because they are able to handle infinitely dimensional spaces.
