Absolute Cesàro summability factors
1993The author proves a theorem on \(|C,1 |_k\) \((k\geq 1)\) summability factors of an infinite series. This includes, as a special case, for \(r_n=1\), a theorem of \textit{K. N. Mishra} and \textit{R. S. L. Srivastava} [Port. Math. 42 (1983/84), 53-61 (1984; Zbl 0597.40003)]. He also uses it to derive a result for \(|N, p_n |_k\) summability.

A note on absolute summability factors.
1998Summary: In this paper we obtain a general theorem on \(\varphi\)-\(|\overline N,p_n; \delta|_k\) summability factors, which generalizes a theorem of H. Bor on \(|\overline N,p_n|_k\) summability factors.
