The $l^{p}$ norms of a class of weighted mean matrices

Peng Gao, Huayu Zhao

We study the $l^{p}$ norms of a class of weighted mean matrices whose diagonal terms are given by $n^{α} / \sum_{i = 1}^{n} i^{α}$ with $α > - 1$ . The $l^{p}$ norms of such matrices are known for…

On Copson's inequalities for $0 < p < 1$

Peng Gao, Huayu Zhao

Let $(λ_{n})_{n \geq 1}$ be a non-negative sequence with $λ_{1} > 0$ and let $Λ_{n} = \sum_{i = 1}^{n} λ_{i}$ . We study the following Copson inequality for $0 < p < 1$ , $L > p$ , \begin{align*} \sum^{\inf…
