Absolute convergence fields of some triangular matrix methods
Arun Kumar, D. P. Sahu · Pacific Journal of Mathematics · 1981
Recently Das [2] has obtained results on the comparison of the absolute convergence fields between the Nδrlund matrix and its product with the Cesaro matrix.In the present paper a similar investigation for the Riesz matrix ((N, p n ) matrix) is made.1* Let A = (α Wlfc ) be an infinite lower triangular matrix, that is a n>k = 0, if k > n, transforming sequence s = {s n } into the sequence -4(8) defined by
