Universal approximation by regular weighted means

Brian Thorpe and Ludwig Tomm

Vol. 117 (1985), No. 2, 443–455
Abstract

In this paper we shall improve upon the results by K. Faulstich, W. Luh and L. Tomm by (i) considering power series representing other meromorphic functions f, (ii) using a regular weighted means method D to obtain the overconvergence property and (iii) showing that D has a universal property with respect to analytic continuation i.e. for every simply connected region G which contains the open disc of convergence of the Maclaurin series of f but no pole of f, there is a subsequence of the D-transform of the n-th partial sums of the Maclaurin series of f that converges to f uniformly on compact subsets of G.
