A General Inclusion Theorem for l-l Nörlund Summability
Published online by Cambridge University Press: 20 November 2018
Abstract
Nӧrlund methods of summability are studied as mappings from I1 into I1. Conditions are given for an arbitrary l-l method to include a Nӧrlund method. In particular necessary and sufficient conditions are given for a row finite l-l method to include a Nӧrlund mean.
