TAUBERIAN THEOREM FOR GENERAL MATRIX SUMMABILITY METHOD

open access: yesUral Mathematical Journal
In this paper, we prove certain Littlewood–Tauberian theorems for general matrix summability method by imposing the Tauberian conditions such as slow oscillation of usual as well as matrix generated sequence, and the De la Vallée Poussin means of real ...

Matrix Transformations between Certain Sequence Spaces over the Non-Newtonian Complex Field [PDF]

open access: yesThe Scientific World Journal, 2014
In some cases, the most general linear operator between two sequence spaces is given by an infinite matrix. So the theory of matrix transformations has always been of great interest in the study of sequence spaces. In the present paper, we introduce the

Summability in anisotropic mixed-norm Hardy spaces

open access: yesElectronic Research Archive, 2022
Let $ H_A^{\vec{p}}(\mathbb{R}^n) $ be the anisotropic mixed-norm Hardy space, where $ \vec{p}\in(0, \infty)^n $ and $ A $ is a general expansive matrix on $ \mathbb{R}^n $.

Matrix Summability of Walsh–Fourier Series

open access: yesMathematics, 2022
The presented paper discusses the matrix summability of the Walsh–Fourier series. In particular, we discuss the convergence of matrix transforms in L1 space and in CW space in terms of modulus of continuity and matrix transform variation.

F-seminorms on generalized double sequence spaces defined by modulus functions; pp. 121–132 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2014
Using a double sequence of modulus functions and a solid double scalar sequence space, we determine F-seminorm and F-norm topologies for certain generalized linear spaces of double sequences.

Necessary and sufficient conditions for matrix summability methods to be stronger than multisummability [PDF]

open access: yesAnnales de l'Institut Fourier, 1996
For general matrix summability methods, we find necessary and sufficient conditions for such methods to be stronger than multisummability. In a second part we show the existence of power series which are not multisummable but can be summed by a matrix method satisfying the conditions mentioned ...

Rainwater-Simons-type convergence theorems for generalized convergence methods [PDF]

open access: yes, 2010
We extend the well-known Rainwater-Simons convergence theorem to various generalized convergence methods such as strong matrix summability, statistical convergence and almost convergence.

Ideal convergence generated by double summability methods

open access: yesDemonstratio Mathematica, 2016
The main result of this note is that if I is an ideal generated by a regular double summability matrix summability method T that is the product of two nonnegative regular matrix methods for single sequences, then I-statistical convergence and convergence

Constructive Matrix Theory [PDF]

open access: yes, 2007
We extend the technique of constructive expansions to compute the connected functions of matrix models in a uniform way as the size of the matrix increases. This provides the main missing ingredient for a non-perturbative construction of the $\phi^{\star

New Definitions about A I -Statistical Convergence with Respect to a Sequence of Modulus Functions and Lacunary Sequences

open access: yesAxioms, 2018
In this paper, using an infinite matrix of complex numbers, a modulus function and a lacunary sequence, we generalize the concept of I -statistical ...
