Absolute Cesàro summability factors of trigonometric series

Rendiconti del Circolo Matematico di Palermo, 1972
The author has extended the definition of |C, α|k (α > -1,k ≥1) and has obtained the summability |C, α|k (α > 1/2, 1≥k >0) of the factored trigonometric series which generalises a result of SinghN. [Proc. Edin. Math. Soc., 16 (1968), 71–76].

Absolute Nörlund summability factors

2005
Let \(\Sigma a_ n\) be a given infinite series with the sequence of partial sums \(\{s_ n\}\). Let \(\{p_ n\}\) be a sequence of constants real or complex, and let us write \(P_ n=p_ 0+p_ 1+\cdots+p_ n\neq 0\), \((n\geq 0)\). The sequence-to-sequence transformation \(\omega_ n={1\over P_ n}\sum^ n_{\nu=0}p_{n-\nu}s_ \nu\) defines the sequence ...

Absolute Cesàro summability factors

1993
The 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.

1998
Summary: 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.
