Generalized absolute matrix summability of infinite series and Fourier series [PDF]
Indian Journal of Pure and Applied Mathematics, 2022 In this paper, two general theorems on absolute matrix summability of infinite series and Fourier series are obtained. Also, two known theorems dealing with vertical bar(N) over bar, p(n)vertical bar(k) summability of infinite series and Fourier series ...

Equivalence Theorem for Absolute Matrix Summability Methods
Mathematical Notes, 2023Suppose that $\sum_{n=0}^{\infty}a_n$ is an infinite series with partial sums $(s_n)$, and $(p_n)$ is a sequence of positive numbers such that $P_n=\sum_{k=0}^{n}p_k\rightarrow\infty$ as $n\rightarrow\infty$, and for all negative subscripts $P_{-n}$, $p_{-n}$ ($n\ge1$) are assumed to be~$0$.

Absolute matrix summability of a factored Fourier series
Proceedings of the Indian Academy of Sciences - Section A, 1993The paper deals with the study of a problem on absolute summability factor of a Fourier series by using triangular matrix means. The result obtained by the authors extends results due to \textit{B. N. Prasad} and \textit{S. N. Bhatt} [Duke Math. J. 24, 103-117 (1957; Zbl 0077.280)] and \textit{S. N. Lal} [Proc. Am. Math. Soc.

A new theorem on generalized absolute matrix summability
2023Summary: In this paper, a general theorem dealing with \(\varphi \)-\( |A,p_n|_k\) summability of an infinite series has been proved by using an almost increasing sequence. Also, some results have been obtained.

On generalized absolute matrix summability
2014Summary: 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.
