A note on the strong regularity of Nrlund means
Published online by Cambridge University Press: 24 October 2008
Extract
Let (pn), (qn) and (un) be sequences of real or complex numbers with
The sequence (sn) is strongly generalized Nrlund summable with index 0, to s, or s or snsN, p, Q if
and pnv=pnvpnv1, with p10. Strong Nrlund summability N, p was first studied by Borweing and Cass (1), and its generalization N, p, Q by Thorp (6). We shall say that (sn) is strongly generalized convergent of index 0, to s, and write snsC, 0, Q if sns and where sn=a0+a1++an. When qn all n, this definition reduces to strong convergence of index , introduced by Hyslop (4). If as n, the sequence (sn) is summable (, q) to s sns(, q).
