Extension of Mazhar’s theorem on summability factors
Keywords:
Absolute Cesàro summability, absolute Riesz summability, bounded linear operators, matrix transformations, summability factors.Abstract
By (X; Y ) we denote the set of all sequences such thatPa nnis summable X wheneverPa n is summable Y , where X and Y are sum-mability methods. In this paper we characterize the set (jC; jk ;N; p n) fork > 1; >References
