Partial best approximations and the absolute Cesaro summability of multiple Fourier series [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 The article is devoted to the problem of absolute Cesaro summability of multiple trigonometric Fourier series. Taking a central place in the theory of Fourier series this problem was developed quite widely in the one-dimensional case and the ...

Application of quasi-f -power increasing sequence in absolute ph - |C, a, b; d; l| of infinite series [PDF]
Mathematica Moravica, 2021 An increasing quasi-f-power sequence of a wider class has been used to establish a universal theorem on a least set of conditions, which is sufficient for an infinite series to be generalized ph-|C, a, b; d; l| k summable.

A study of bounded operators on martingale Hardy spaces [PDF]
, 2021 The classical Fourier Analysis has been developed in an almost unbelievable way from the first fundamental discoveries by Fourier. Especially a number of wonderful results have been proved and new directions of such research has been developed e.g ...

A study on absolute summability factors
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020 In this study we proved theorems dealing withsummability factors giving relations between absolute Cesàro and absolute weightedsummability methods. So we deduced some results in the special cases.

Spectral properties of substitutions on compact alphabets
Bulletin of the London Mathematical Society, Volume 55, Issue 5, Page 2425-2445, October 2023., 2023 Abstract We consider substitutions on compact alphabets and provide sufficient conditions for the diffraction to be pure point, absolutely continuous and singular continuous. This allows one to construct examples for which the Koopman operator on the associated function space has specific spectral components.

Numerical Methods for Partial Differential Equations, Volume 39, Issue 5, Page 3777-3810, September 2023., 2023 Abstract Recently developed concept of dissipative measure‐valued solution for compressible flows is a suitable tool to describe oscillations and singularities possibly developed in solutions of multidimensional Euler equations. In this paper we study the convergence of the first‐order finite volume method based on the exact Riemann solver for the ...

Counting and boundary limit theorems for representations of Gromov‐hyperbolic groups
Proceedings of the London Mathematical Society, Volume 127, Issue 3, Page 589-652, September 2023., 2023 Abstract Given a Gromov‐hyperbolic group G$G$ endowed with a finite symmetric generating set, we study the statistics of counting measures on the spheres of the associated Cayley graph under linear representations of G$G$. More generally, we obtain a weak law of large numbers for subadditive functions, echoing the classical Fekete lemma.
