A converse to Littlewood-type theorem for random Dirichlet series

Abstract

This article investigates random Dirichlet series within the framework of Hardy and mixed norm spaces of Dirichlet series. We completely characterize when the random symbol space of the Hardy space ℋp coincides with ℋ2. In the setting of mixed norm spaces ℋp,qα, the corresponding characterizations for the random symbol space of ℋp,qα coinciding with ℋ2,qα are given when q≥4, and some sufficient and necessary conditions are established when q<4. We also obtain some integrability results when Dirichlet series belong to the corresponding random symbol spaces.
