Abstract

In an earlier paper Savas and Rhoades [Ekrem Savaş, B.E. Rhoades, A note on | A |k summability factors, Nonlinear Anal. 66 (2007) 1879-1883. [1]] obtained a summability factor theorem for absolute summability of order k ≥ 1. In this paper we extend that result to doubly infinite matrices. © 2008 Elsevier Ltd. All rights reserved.
