Özet

In an earlier paper the first author [Ekrem Savas, Factors for | A |k summability of infinite series, Comput. Math. Appl. 53 (7) (2007) 1045-1049. [3]] obtained a summability factor theorem for absolute summability of the order k ≥ 1. In this paper we extend that result to doubly infinite matrices. © 2007 Elsevier Ltd. All rights reserved.
