On a Recent Result on Absolute Surnmability Factors

Abstract

In this paper, a general theorem of vertical bar A vertical bar(k) summability factors is presented. This generalization is accomplished by replacing the weighted mean matrix in Mazhar's theorem in [S.M. Mazhar, A remark on a recent result on absolute summability factors, Indian J. Math. 40 (2) (1998) 123-13 1] with a triangular matrix. (c) 2005 Published by Elsevier Ltd
