In the present paper we obtain sufficient conditions for a series ? an. which is absolutely summable of order k by a weighted mean method to be such that ? an? n is absolutely summable of order x by a triangular matrix. As corollary of this result we obtain an inclusion theorem. © ELEMENT.eninfo:eu-repo/semantics/closedAccessAbsolute summabilitySummability factorWeighted mean matrixArticle102365370Q4WOS:000246189200016Q22-s2.0-3424858465710.7153/mia-10-34
