Acta et Commentationes Universitatis Tartuensis AB - The series ∑Uk is said to be summable (Eλ,q) to u, if λn(En q−u)=o(1), where En q denotes the Euler-Knopp transform of the sequence of partial sums of the series, and λ={λn} is a positive increasing sequence. It is shown that all the methods (Eλ,q),...
