A Note on Absolute Cesaro $\varphi-|C, 1; \delta; l|_k$ Summability Factor
International Journal of Analysis and Applications, 2017 A positive non-decreasing sequence has been used to establish a theorem on a minimal set of sufficient conditions for an infinite series to be absolute Cesaro $\varphi-|C, 1; \delta; l|_k$ summable.

Local spectral theory for subordinated operators: The Cesàro operator and beyond
Journal of the London Mathematical Society, Volume 112, Issue 2, August 2025.Abstract We study local spectral properties for subordinated operators arising from C0$C_0$‐semigroups. Specifically, if T=(Tt)t⩾0$\mathcal {T}=(T_t)_{t\geqslant 0}$ is a C0$C_0$‐semigroup acting boundedly on a complex Banach space and Hν=∫0∞Ttdν(t)$$\begin{equation*} \mathcal {H}_\nu = \int _{0}^{\infty } T_t\; d\nu (t) \end{equation*}$$is the ...

Tauberian theorems for Cesàro summability of sequences of fuzzy numbers
, 2014 In this paper we use the concept of the Cesàro convergence of a sequence of fuzzy numbers defined by Subrahmanyam [Cesàro summability of fuzzy real numbers, Anal, 7 (1999), 159-168] to prove some Tauberian theorems for sequences of fuzzy numbers 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 ...

Cesàro and Borel-type summability
, 1988 Though summability of a series by the Cesàro method C p {C_p} does not in general imply its summability by the Borel-type method ( B , α , β )

MathematicsThis paper generalizes stochastic sampled-data synchronization of reaction–diffusion neural networks (RDNNs) from sampling distributions with finite support to infinite discrete distributions, whose sampling intervals are drawn from a countably infinite ...

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 ...

Rigorous data‐driven computation of spectral properties of Koopman operators for dynamical systems
Communications on Pure and Applied Mathematics, Volume 77, Issue 1, Page 221-283, January 2024.Abstract Koopman operators are infinite‐dimensional operators that globally linearize nonlinear dynamical systems, making their spectral information valuable for understanding dynamics. However, Koopman operators can have continuous spectra and infinite‐dimensional invariant subspaces, making computing their spectral information a considerable ...

Some further extensions of absolute Cesàro summability for double series [PDF]
, 2013 In a recent paper [SavaAY and Rhoades in Appl. Math. Lett. 22:1462-1466, 2009], the authors extended the result of Flett [Proc. Lond. Math. Soc. 7:113-141, 1957] to double summability.

Extension of Mazhar’s theorem on summability factors
Kuwait Journal of Science, 2015 By (X; Y ) we denote the set of all sequences such thatPa nnis summable X wheneverPa n is summable Y , where X and Y are sum-mability methods. In this paper we characterize the set (jC; jk ;N; p n) fork > 1; > 1 and arbitrary positive ...
