Es. Katsoprinakis et M. Papadimitrakis, Extensions of a theorem of Marcinkiewicz-Zygmund and of Rogosinski's formula and an application to universal Taylor series, P AM MATH S, 127(7), 1999, pp. 2083-2090
This paper extends Rogosinski's formula and the Marcinkiewicz-Zygmund Theor
em about circular structure of the limit points of the partial sums of (C,1
) summable Taylor series. Also a result about summability of H-p Taylor ser
ies is proved and an application on Universal Taylor series is given.
