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 ...

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 noncommutative distributional Khintchine type inequalities

Bulletin of the London Mathematical Society, Volume 56, Issue 7, Page 2278-2295, July 2024.
Abstract The purpose of this paper is to provide distributional estimates for the series of the form ∑k=1∞xk⊗rk$\sum _{k=1}^\infty x_k\otimes r_k$ with {xk}k⩾1$\lbrace x_k\rbrace _{k\geqslant 1}$ being elements from noncommutative Lorentz spaces Λlog1/2(M)$\Lambda _{\log ^{1/2}}(\mathcal {M})$ and {rk}k⩾1$\lbrace r_k\rbrace _{k\geqslant 1}$ being ...

Degree of approximation of functions belonging to Lipα class and weighted (L^r,ξ(t)) class by product summability method [PDF]

Surveys in Mathematics and its Applications, 2010
A good amount of work has been done on degree of approximation of functions belonging to Lipα, Lip(α,r), Lip(ξ(t),r) and W(Lr, ξ(t)) classes using Cesàro and (generalized) Nörlund single summability methods by a number of researchers like Alexits, Sahney,
