A Summability Factor Theorem for Generalized Absolute Summability

open access: yesReal Analysis Exchange, 2006
In this paper, we establish a summability factor theorem for summability |A, |k as defined in (1) where A is a lower triangular matrix with non-negative entries satisfying certain conditions. Our paper is an extension of the main result of [1] using definition (1) below.
