Rhoades, B. E.; Savaş, Ekrem On summability factors for \(|\overline N, p_n|_k\). (English) Zbl 1120.40002 Adv. Dyn. Syst. Appl. 1, No. 1, 79-89 (2006). The authors generalize the result of N. Singh and N. Sharma [Proc. Indian Acad. Sci., Math. Sci. 110, 61-68 (2000; Zbl 0946.40002)]. They prove necessary and sufficient conditions for \(\sum a_{n}\lambda _{n}\) to be \( \left| N,q\right| _{k}\) summable with \(k>1,\) whenever \(\sum a_{n}\) is \(\left| N,p,q\right| _{k}\)summable. There are no definitions of \(\left| N,q\right| _{k}\) and \(\left| N,p,q\right| _{k}\) methods.
