Traces of H\"ormander algebras on discrete sequences

Complex Variables 2010-04-16 v1

Abstract

We show that a discrete sequence Λ\Lambda of the complex plane is the union of nn interpolating sequences for the H\"ormander algebras ApA_p if and only if the trace of ApA_p on Λ\Lambda coincides with the space of functions on Λ\Lambda for which the divided differences of order n1n-1 are uniformly bounded. The analogous result holds in the unit disk for Korenblum-type algebras.
