We obtain sufficient conditions for the series∑anλnto be absolutely summable of orderkby a triangular matrix.
Recently, we have proved a main theorem dealing with the absolute Nörlund summability factors of infinite series by using -quasimonotone sequences. In this paper, we prove that result under weaker conditions. A new result has also been obtained.
