On a Class of Positive Linear Operators

Abstract

In a recent paper [3] Meir and Sharma introduced a generalization of the S α - method of summability. The elements of their matrix, ( a nk ), are defined by (1) where is a sequence of complex numbers. if 0 < α j < l for each j = 0, 1, 2,… then a nk ≥0 for each n = 0, 1, 2,… and k = 0,1,2,…
