Some class of nonlinear inequalities with gradient constraints in Orlicz spaces

Moroccan Journal of Pure and Applied Analysis, 2020
In the present paper, we show the existence of solutions of some nonlinear inequalities of the form 〈Au + g(x, u,∇ u), v −u〉 ≥〈 f, v −u〉 with gradient constraint that depend on the solution itself, where A is a Leray-Lions operator defined on Orlicz ...

Nonlinear sampling Durrmeyer operators: approximation results in function spaces

Advanced Nonlinear Studies
In this paper we introduce and study the nonlinear version of sampling Durrmeyer operators. For what concerns the space of continuous functions, a pointwise and uniform convergence theorem have been established.

The molecular characterization of anisotropic Herz-type Hardy spaces with two variable exponents

Open Mathematics, 2020
In this article, the authors establish the characterizations of a class of anisotropic Herz-type Hardy spaces with two variable exponents associated with a non-isotropic dilation on ℝn{{\mathbb{R}}}^{n} in terms of molecular decompositions.

Introduction to the spectral theory of Toeplitz operators

Concrete Operators
We provide a brief introduction to the spectral theory of Toeplitz operators on Hardy spaces built upon L p-spaces and their abstract generalisations.

The spectrum generated by s-numbers and pre-quasi normed Orlicz-Cesáro mean sequence spaces

Open Mathematics, 2020
In this article, we study some topological properties of the multiplication operator on Orlicz-Cesáro mean sequence spaces equipped with the pre-quasi norm and the pre-quasi operator ideal constructed by this sequence space and s-numbers.

Korovkin type approximation for double sequences via statistical A-summation process on modular spaces

, 2018
n this work, we introduce the Korovkin type approximation theorems on modular spaces via statistical A-summation process for double sequences of positive linear operators and we construct an example satisfying our new approximation theorem but does not ...

Continuity and essential norm of operators defined by infinite tridiagonal matrices in weighted Orlicz and l∞ spaces

Open Mathematics
In this article, we provide a comprehensive study on the continuity and essential norm of an operator defined by an infinite tridiagonal matrix, specifically when it operates from a weighted Orlicz sequence space or a weighted l∞{l}^{\infty } space into ...

İzotropik Olmayan Potansiyel Teorik Eşitsizlik

, 2018
In this paper, the new weighted inequalities were derived by ?-distance which is similar to the given inequality for the potential operator defined in [1]. The results presented here would provide extensions of those given in earlier works.
