Tauberian conditions with controlled oscillatory behavior for statistical convergence

open access: yesFilomat, 2018
We present new Tauberian conditions in terms of the general logarithmic control modulo of the oscillatory behavior of a real sequence (sn) to obtain lim n?? sn = ? from st - lim n?? sn = ?, where ? is a finite number. We also introduce the statistical (l,m) summability method and extend some Tauberian theorems to this method.

On the weighted generator of double sequences and its Tauberian conditions

open access: yesAdvances in Operator Theory, 2023
Let \(w^2(\mathbb{K})\), \(w(\mathbb{R}^{>0})\), \(c^2(\mathbb{K})\) and \(\ell_{\infty}^2(\mathbb{K})\) denote the set of all double sequences, the set of all single sequences of positive real numbers, the set of all P-convergent (convergent in Pringsheim's sense) double sequences and the set of all bounded double sequences, respectively. The weighted

Tauberian theorems for (N̄, p, q, w) summable triple sequences of fuzzy numbers

open access: yesCQD Revista Eletrônica Paulista de Matemática
In this paper, we introduce the notion of weighted mean method (N̄, p, q, w) of triple sequences of fuzzy numbers and and show necessary and sufficient Tauberian conditions under which convergence in Pringsheim's sense of a triple sequence of fuzzy ...

A New Notion of Convergence Defined by The Fibonacci Sequence: A Novel Framework and Its Tauberian Conditions

open access: yesMathematics
The Fibonacci sequence has broad applications in mathematics, where its inherent patterns and properties are utilized to solve various problems. The sequence often emerges in areas involving growth patterns, series, and recursive relationships.

A remark on the Wiener-Ikehara Tauberian theorem [PDF]

open access: yes, 2014
In this paper we point out that the proof of Kable's extension of the Wiener-Ikehara Tauberian theorem can be applied to the case where the Dirichlet series has a pole of order "$l / m$" without much modification (Kable proved the case $l = 1$).Comment ...

General Tauberian conditions for weighted mean methods of summability [PDF]

open access: yesJournal of Classical Analysis, 2019
Summary: In this paper we recover convergence of a complex sequence \((u_n)\) out of its summability by weighted means under certain supplementary conditions that control the oscillatory behavior of \((u_n)\). As corollaries, we obtain classical Hardy-type Tauberian conditions for various weighted mean methods.

On a Tauberian theorem for the weighted mean method of summability

open access: yesKuwait Journal of Science, 2015
We investigate conditions needed for a weighted mean summable series to beconvergent by using Kloosterman’s method. The results of this paper generalize thewell known results of Landau and Hardy.

Asymptotic expansions relating to the distribution of the length of longest increasing subsequences

open access: yesForum of Mathematics, Sigma
We study the distribution of the length of longest increasing subsequences in random permutations of n integers as n grows large and establish an asymptotic expansion in powers of $n^{-1/3}$ .

A Note on Tauberian Conditions for Abel and Cesaro Summability [PDF]

open access: yesProceedings of the American Mathematical Society, 1955
A conjecture has recently been made by P. L. Butzerl that there exist Tauberian conditions for the Cesaro method of summability which are not also Tauberian conditions for Abel summability. It was pointed out2 by G. Lorentz that the conjecture is true in a trivial sense if we define the Tauberian condition as membership of a class T consisting of all ...
