Norm convergence of partial sums of $H^1$ functions

Complex Variables 2018-04-13 v2

Abstract

A classical observation of Riesz says that truncations of a general n=0anzn\sum_{n=0}^\infty a_n z^n in the Hardy space H1H^1 do not converge in H1H^1. A substitute positive result is proved: these partial sums always converge in the Bergman norm A1A^1. The result is extended to complete Reinhardt domains in \Cn\C^n. A new proof of the failure of H1H^1 convergence is also given.
