Sets of values of general Dirichlet series
\textit{Harald Bohr} [Math. Ann. 79, 136--156 (1919; JFM 46.0490.01)] gave four theorems on the set of values of a general Dirichlet series \(f(s) = \sum_{n=1}^\infty a_n e^{-\lambda_ns}\), where \(\lambda_{n+1} > \lambda_n\), \(\lambda_n\to +\infty\), taken along a given vertical line or in its neighborhood.

REGULAR GROWTH OF DIRICHLET SERIES OF THE CLASS 𝐷(Φ) ON CURVES OF BOUNDED 𝐾-SLOPE
We study the asymptotic behavior of the sum of en- tire Dirichlet series with positive exponents on curves of a bounded slope going in a certain way to infinity.

Series with Commuting Terms in Topologized Semigroups
We show that the following general version of the Riemann–Dirichlet theorem is true: if every rearrangement of a series with pairwise commuting terms in a Hausdorff topologized semigroup converges, then its sum range is a singleton.

A D-N alternating algorithm for exterior 3-D problem with ellipsoidal artificial boundary
In this study, based on a general ellipsoidal artificial boundary, we present a Dirichlet-Neumann (D-N) alternating algorithm for exterior three dimensional (3-D) Poisson problem.

On the uniqueness of nonlinear diffusion coefficients in the presence of lower order terms [PDF]
We consider the identification of nonlinear diffusion coefficients of the form $a(t,u)$ or $a(u)$ in quasi-linear parabolic and elliptic equations. Uniqueness for this inverse problem is established under very general assumptions using partial knowledge ...

A generalization of Bohr's Equivalence Theorem [PDF]
Based on a generalization of Bohr's equivalence relation for general Dirichlet series, in this paper we study the sets of values taken by certain classes of equivalent almost periodic functions in their strips of almost periodicity.

A converse theorem for double Dirichlet series and Shintani zeta functions [PDF]
The main aim of this paper is to obtain a converse theorem for double Dirichlet series and use it to show that the Shintani zeta functions which arise in the theory of prehomogeneous vector spaces are actually linear combinations of Mellin transforms of ...
