| Abstract: | 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. |
