Description
In an earlier paper (Rhoades, B. E. and Savas, E. Some necessary conditions for absolute matrix summability factors. Indian J. Pure Appl. Math., 2002, 33(7), 1003-1009) the authors obtained necessary conditions for the series Sigma a(n) to be absolutely summable of order k by a triangular matrix. In this paper we present sufficient conditions for absolute matrix summability factors. As a corollary we obtain a result of N. Singh (On vertical bar(N) over bar, p(n)vertical bar summability factors of infinite series. Indian J. Math., 1968, 10, 19-24).
