Abstract

Quite recently Bor [H. Bor, An application of almost increasing and δ-quasi-monotone sequences, JIPAM. J. Inequal. Pure Appl. Math. 1 (2) (2000). Article 18, 6 pp.] has proved a theorem on | over(N, -) pn |k-summability factors of an infinite series. The present paper deals with a further generalization of his result. © 2008 Elsevier Ltd.
