Abstract

For a real number α\alpha the Hilbert spaces Dα\mathscr{D}_\alpha consists of those Dirichlet series n=1an/ns\sum_{n=1}^\infty a_n/n^s for which n=1an2/[d(n)]α<\sum_{n=1}^\infty |a_n|^2/[d(n)]^\alpha < \infty, where d(n)d(n) denotes the number of divisors of nn. We extend a theorem of Seip on the bounded zero sequences of functions in Dα\mathscr{D}_\alpha to the case α>0\alpha>0. Generalizations to other weighted spaces of Dirichlet series are also discussed, as are partial results on the zeros of functions in the Hardy spaces of Dirichlet series Hp\mathscr{H}^p, for 1p<21\leq p <2.
