Hardy spaces of general Dirichlet series — a survey [PDF]

open access: bronzeBanach Center Publications, 2019
The main purpose of this article is to survey on some key elements of a recent $\mathcal{H}_p$-theory of general Dirichlet series $\sum a_n e^{- _{n}s}$, which was mainly inspired by the work of Bayart and Helson on ordinary Dirichlet series $\sum a_n n^{-s}$.

Weighted inversion of general Dirichlet series [PDF]

open access: hybridTransactions of the American Mathematical Society, 2013
Inversion theorems of Wiener type are essential tools in analysis and number theory. We derive a weighted version of an inversion theorem of Wiener type for general Dirichlet series from that of Edwards from 1957, and we outline an alternative proof based on the duality theory of convex cones and extension techniques for characters of semigroups ...

Multilevel Evaluation of the General Dirichlet Series

open access: diamondAdvances in the Theory of Nonlinear Analysis and its Application, 2020
In this Study, an accurate method for summing the general Dirichlet series is presented. Long range terms of this series are calculated by a multilevel approach. The Dirichlet series, in this technique, is decomposed into two parts, a local part and a smooth part.

On universality of general Dirichlet series [PDF]

open access: green
In the present work, we establish sufficient conditions for a Dirichlet series induced by general frequencies to be universal with respect to vertical translations. Our results can be applied to known universal objects such as Hurwitz zeta functions and also can provide new examples of universal Dirichlet series including the alternating prime zeta ...

$$\pmb {{\mathcal {H}}_{p}}$$-Theory of General Dirichlet Series

open access: closedJournal of Fourier Analysis and Applications, 2019
Inspired by results of Bayart on ordinary Dirichlet series $\sum a_n n^{-s}$, the main purpose of this article is to start an $\mathcal{H}_p$-theory of general Dirichlet series $\sum a_n e^{- _{n}s}$. Whereas the $\mathcal{H}_p$-theory of ordinary Dirichlet series, in view of an ingenious identification of Bohr, can be seen as a sub-theory of Fourier ...
