Some Banach spaces of Dirichlet series

The Hardy spaces of Dirichlet series denoted by ${\cal H}^p$ ($p\ge1$) have been studied in [12] when p = 2 and in [3] for the general case. In this paper we study some Lp-generalizations of spaces of Dirichlet series, particularly two families of Bergman spaces denoted ${\cal A}^p$ and ${\cal B}^p$. We recover classical properties of spaces of analytic functions: boundedness of point evaluation, embeddings between these spaces and "Littlewood-Paley" formulas when p = 2. We also show that the ${\cal B}^p$ spaces have properties similar to the classical Bergman spaces of the unit disk while the ${\cal A}^p$ spaces have a different behavior.
