A study on generalized absolute summability factors for a triangular matrix; pp. 115–120 [PDF]

Proceedings of the Estonian Academy of Sciences, 2011
In this paper, we establish a summability factor theorem for summability |A, δ|k. This paper is an extension of the main result of Savas, E. A study on absolute summability factors for a triangular matrix. Math. Ineq. Appl., 2009, 12(19), 141–146.

Local properties of absolute matrix summability of factored fourier series

Filomat, 2017
In this paper, we introduce two new general theorems on ??A,pn?k summability factors of infinite and Fourier series. By using these theorems, we obtain some new results regarding other important summability methods and investigate conversions between them.

Paranormed spaces of absolute tribonacci summable series and some matrix transformations

Dera Natung Government College Research Journal
In a more recent paper, the absolute series space I T_\Phi I_q   which is defined as the domain of the matrix corresponding to the absolute Tribonacci summability in the well-known space l_q has taken place in the literature (Gökçe, in press).

ON GENERALIZED ABSOLUTE MATRIX SUMMABILITY

, 2014
Summary: In this paper a general theorem on \(| A,p_{n};\delta|_{k}\) summability factors, which generalizes a theorem of \textit{H. Bor} [Kuwait J. Sci. Eng. 23, No. 1, 1--5 (1996; Zbl 0849.40003)] on \(\left|\bar{N},p_ {n}\right|_{k}\) summability factors, has been proved under weaker conditions by using an almost increasing sequence.

On Generalized Absolute Matrix Summability of Infinite Series

Communications in Mathematics and Applications, 2019
In this paper, we have generalized a known theorem on \(|\bar{N},p_n|_{k}\) summability factors of infinite series with a new summability method by using almost increasing sequences. This new theorem also includes several new and known results.
