On absolute summability factors of infinite series

In this paper a general theorem on |A,δ|k|A,δ|k-summability methods has been proved. This theorem includes, as a special case, a known result in [E. Savas, Factors for |A|k|A|k Summability of infinite series, Comput. Math. Appl. 53 (2007) 1045–1049].
