On Modulated Lacunary Statistical Convergence of Double Sequences

open access: yesMathematics, 2023
In earlier works, F. León and coworkers discovered a remarkable structure between statistical convergence and strong Cesàro convergence, modulated by a function f (called a modulus function).

New Construction and New Error Bounds for (0, 2, 4) Lacunary Interpolation By Six Degree Spline [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2011
The object of this paper obtains the existence, uniqueness and upper bounds for errors of six degree splines interpolating the lacunary data (0, 2, 4). We also show that the changes of  the boundary conditions and the class of spline functions has a main

TOMIC FUNCTIONS AND LACUNARY INTERPOLATION SERIES IN BOUNDARY VALUE PROBLEMS FOR PARTIAL DERIVATIVES EQUATIONS AND IMAGE PROCESSING

open access: yesРадіоелектронні і комп'ютерні системи, 2020
In the paper we consider and solve the problem of construction of the so called tomic functions – the systems of infinitely differentiable  functions which while retaining many important properties of the shifts of atomic function up(x) such as locality ...

Hervé- and Krebs-Type Magnetic Polyoxometalate Dimers

open access: yesMagnetochemistry, 2022
Lacunary polyoxometalates (POMs) are negatively charged metal–oxo clusters, formally obtained from plenary topologies via fragment removal. Owing to the fragment removal, the lacunary POMs archetypes are rich in nucleophilic terminal oxo ligands, making ...

Some new lacunary statistical convergence with ideals

open access: yesJournal of Inequalities and Applications, 2017
In this paper, the idea of lacunary I λ $I_{\lambda}$ -statistical convergent sequence spaces is discussed which is defined by a Musielak-Orlicz function.

Lacunary Fourier series and a qualitative uncertainty principle for compact Lie groups [PDF]

open access: yes, 2010
We define lacunary Fourier series on a compact connected semisimple Lie group $G$. If $f \in L^1(G)$ has lacunary Fourier series, and vanishes on a non empty open set, then we prove that $f$ vanishes identically.

I2-lacunary strongly summability for multidimensional measurable functions [PDF]

open access: yesPublications de l'Institut Mathematique, 2020
Let I2 ? P(N ? N) be a nontrivial ideal. We provide a new approach to the concept of I2-double lacunary statistical convergence and I2-lacunary strongly double summable by taking f(?,?), which is a multidimensional measurable real valued function on (1,?) ? (1,?). Additionally, we examine the relation between these two new methods.

Kolyada inequality for partial moduli of smoothness of functions with lacunary Fourier coefficients [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2022
The problem of estimating the moduli of smoothness of functions from $L_q$  in terms of moduli of smoothness from $L_p$  is well known. The initial stage in estimating the moduli of smoothness was the study of properties of functions from ...
