Özet

In this paper we prove a general theorem on | A ; δ |k-summability factors of infinite series under suitable conditions by using an almost increasing sequence, where A is a lower triangular matrix with non-negative entries. Also, we deduce a similar result for the weighted mean method. © 2007 Elsevier Ltd. All rights reserved.
