Characterizations of summability methods derived by q-Cesàro matrix

Dera Natung Government College Research Journal
The present study  mainly aims to introduce the absolute summability method  derived  from the transformation matrix  obtained by the -Cesàro matrix   and   to establish  the  necessary and sufficient conditions for and   where   In addition, by ...

Bootstrapping non‐stationary and irregular time series using singular spectral analysis

Journal of Time Series Analysis, Volume 46, Issue 1, Page 81-112, January 2025.
This article investigates the consequences of using Singular Spectral Analysis (SSA) to construct a time series bootstrap. The bootstrap replications are obtained via a SSA decomposition obtained using rescaled trajectories (RT‐SSA), a procedure that is particularly useful in the analysis of time series that exhibit nonlinear, non‐stationary and ...

I_2-Cesàro summability of double sequences of sets [PDF]

, 2015
In this paper, we de ned concept of Wijsman I2-Cesàro summability and investigate the relationship between the concepts of Wijsman strongly I2-Cesàro summability, Wijsman strongly I2-lacunary convergence, Wijsman p-strongly I2-Cesàro summability and ...

Elzaki Transform Approach to Fractional Kinetic Equations Using Orthogonal Polynomials and Their Generating Functions

Advances in Mathematical Physics, Volume 2025, Issue 1, 2025.
Various significant problems in physics and astrophysics have been successfully solved using fractional kinetic equations (FKEs) and special functions. This study applies the Elzaki integral transform to FKEs incorporating orthogonal polynomials and their generating functions.

Regularity and asymptotics of densities of inverse subordinators

Transactions of the London Mathematical Society, Volume 11, Issue 1, December 2024.
Abstract In this article, densities (and their derivatives) of subordinators and inverse subordinators are considered. Under minor restrictions, generally milder than the existing in the literature, employing a useful modification of the saddle point method, we obtain the large asymptotic behaviour of these densities (and their derivatives) for a ...

Trigonometric Approximation of Signals (Functions) Belonging to W(Lr, ξ(t)) Class by Matrix (C1·Np) Operator

International Journal of Mathematics and Mathematical Sciences, 2012
Various investigators such as Khan (1974), Chandra (2002), and Liendler (2005) have determined the degree of approximation of 2π-periodic signals (functions) belonging to Lip(α,r) class of functions through trigonometric Fourier approximation using ...

Ergodic properties of multiplication and weighted composition operators on spaces of holomorphic functions

Mathematische Nachrichten, Volume 297, Issue 7, Page 2609-2623, July 2024.
Abstract We obtain different results about the mean ergodicity of weighted composition operators when acting on the spaces H(B)$H(B)$, Hb(B)$H_b(B)$, and H∞(B)$H^\infty (B)$, where B$B$ is the open unit ball of a Banach space, as well as about the compactness and the mean ergodicity of the multiplication operator. This study relates these properties of

On the $\Delta _{{\Lambda ^2}}^f$-Statistical Convergence on Product Time Scale

Universal Journal of Mathematics and Applications, 2020
In this paper, we first define a new density of a $\Delta $-measurable subset of a product time scale ${\Lambda ^2}$ with respect to an unbounded modulus function.
