A new note on absolute Riesz summability
In the present paper, by using an almost increasing sequence a known theorem dealing with vertical bar(N) over bar, p(n)vertical bar(k) summability factors of infinite series has been generalized to the vertical bar(N) over bar, p(n), theta(n)vertical bar(k) summability. This new theorem also includes several new results. (C) 2011 Elsevier Ltd. All rights reserved.
