On \(| A| _k\) summability factors. (English) Zbl 1121.40009

In this paper the author proved a summability factor theorem for summability \(| A| _k\) where \(k\geq 1\), and lower triangular matrix with non-negative entries satisfying certain condition. The theorem is an generalization of the result of S. M. Mazhar [Kyungpook. Math. J. 39,67–73 (1999; Zbl 0932.40006)].
