A note on generalized absolute Cesàro summability

open access: yes, 2010
In this paper, a known theorem dealing with ${\mid{C},1\mid}_k$ summability methods has been generalized under weaker conditions for ${\mid{C},\alpha,\beta\ ;\delta\mid}_k$ summability methods.

Factors for generalized absolute Cesàro summability

open access: yes, 2008
In this paper, a result of Bor [2] dealing with ${\mid{C,\alpha;\beta}\mid}_k$ summability factors has been generalized for ${\mid{C},\alpha, \gamma;\beta\mid}_k$ summability ...

A Note On The Matrix Operators Of Absolute Nörlund Series Space

open access: yes, 2023
On the recent study, the series spaceNθp ∣(q) has been introduced as the set of all series summable by the absolute Nörlund summability method, which includes the Maddox’s space l(q), the absolute Cesàro space |Cα |k and the absolute Nörlund space∣ ∣Nθ ...

Absolute Summability Factors in a Sequence

open access: yes, 1984
Let α≥0 and β>— 1. The main result gives necessary and sufficient conditions for the sequence (εn) in order that the sequence (εnUn) will be absolutely summable by the Cesàro method Cβ for each sequence (Un) which is bounded or summable by the method ...

On Absolute Summability by Riesz and Generalized Cesàro Means. II

open access: yes, 1970
1. We will use the terminology of part I [9], including the general assumptions of [9, § 1]. In that paper we had proved that |R, λ, κ| = |C, λ, κ| in case that κ is an integer.
