Abstract

The purpose of this paper is to determine the conditions for which Sigmaa(n)lambda(nu) is summable \T\(s) whenever Sigmaa(n) is summable \(N) over bar ,p(n)\(k) where T is a lower triangular matrix with positive entries and row sums one. As special cases we obtain inclusion theorems for pairs of weighted mean matrices.
