Necessary conditions for absolute matrix summability methods
Bollettino dell'Unione Matematica Italiana, 2015The authors obtain necessary conditions in order that a series \(\sum a_{n}\) should be summable \(|B,q_{n}|_{k}\) whenever \(\sum a_{n}\) is summable \( |A,p_{n}|_{k}\) as a generalization of the result of \textit{H. Bor} and \textit{B. Thorpe} [Analysis 12, No. 1--2, 1--3 (1992; Zbl 0753.40007)].

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.
