Comparison of speeds of convergence in Riesz‐type families of summability methods. II

open access: yesMathematical Modelling and Analysis, 2010
Certain summability methods for functions and sequences are compared by their speeds of convergence. The authors are extending their results published in paper [9] for Riesz‐type families {Aα} (α > α0 ) of summability methods Aα .

Tauberian class estimates for vector-valued distributions [PDF]

open access: yes, 2019
We study Tauberian properties of regularizing transforms of vector-valued tempered distributions, that is, transforms of the form $M^{\mathbf{f}}_{\varphi}(x,y)=(\mathbf{f}\ast\varphi_{y})(x)$, where the kernel $\varphi$ is a test function and $\varphi_ ...

Análogos a Teoremas Tauberianos

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2011
We obtain some results similar to W. Rudin’s Tauberian Theorem, on singular integrals defined on bounded intervals.

Wiener Tauberian theorems for vector-valued functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Different versions of Wiener's Tauberian theorem are discussed for the generalized group algebra L1(G,A) (of integrable functions on a locally compact abelian group G taking values in a commutative semisimple regular Banach algebra A) using A-valued ...

Unbounded Versions of Two Old Summability Theorems

open access: yesAxioms, 2023
In this note, we obtain extensions of a theorem of Meyer-König and Zeller and a theorem of Wilansky in that the given results do not require a summability matrix to be a bounded operator from the convergent sequences into themselves.

Tauberian theorem for value functions [PDF]

open access: yes, 2017
For two-person dynamic zero-sum games (both discrete and continuous settings), we investigate the limit of value functions of finite horizon games with long run average cost as the time horizon tends to infinity and the limit of value functions of ...

Tauberian conditions for Conull spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
The typical Tauberian theorem asserts that a particular summability method cannot map any divergent member of a given set of sequences into a convergent sequence. These sets of sequences are typically defined by an “order growth” or “gap” condition.

DISTRIBUTION OF VALUES OF THE SUM OF UNITARY DIVISORS IN RESIDUE CLASSES

open access: yesПроблемы анализа, 2016
In this paper we prove the tauberian type theorem containing the asymptotic series for the Dirichlet series. We use this result to study distribution of sum of unitary divisors in residue classes coprime with a module.

Generalized Euler‐Knopp method and convergence acceleration

open access: yesMathematical Modelling and Analysis, 2006
New propositions on λ‐boundedness for generalized Euler‐Knopp method of summability (ϵ, T), where ? is a linear bounded operator from Banach space X into X, are proved.

Tauberian conditions, Muckenhoupt weights, and differentiation properties of weighted bases [PDF]

open access: yes, 2013
We give an alternative characterization of the class of Muckenhoupt weights $A_{\infty, \mathfrak B}$ for homothecy invariant Muckenhoupt bases $\mathfrak B$ consisting of convex sets. In particular we show that $w\in A_{\infty, \mathfrak B}$ if and only
