Local properties of Hilbert spaces of Dirichlet series

TL;DR

This paper investigates how the asymptotic behavior of positive sequences influences the local properties of Hilbert spaces of Dirichlet series, connecting number theory, function spaces, and infinite-dimensional analysis.

Contribution

It extends existing results by linking partial sum asymptotics to local space properties, including boundary behavior and interpolation, in infinite-dimensional settings.

Findings

Asymptotic partial sums determine local space behavior

Connections established between Dirichlet, Bergman, and Besov-Sobolev spaces

New insights into infinite-dimensional function spaces and their boundary properties

Abstract

We show that the asymptotic behavior of the partial sums of a sequence of positive numbers determine the local behavior of the Hilbert space of Dirichlet series defined using these as weights. This extends results recently obtained describing the local behavior of Dirichlet series with square summable coefficients in terms of local integrability, boundary behavior, Carleson measures and interpolating sequences. As these spaces can be identified with functions spaces on the infinite-dimensional polydisk, this gives new results on the Dirichlet and Bergman spaces on the infinite dimensional polydisk, as well as the scale of Besov-Sobolev spaces containing the Drury-Arveson space on the infinite dimensional unit ball. We use both techniques from the theory of sampling in Paley-Wiener spaces, and classical results from analytic number theory.
