Zeros of $L (s) + L (2 s) + \dots + L (N s)$ in the region of absolute convergence

Łukasz Pańkowski, Mattia Righetti

In this paper we show that for every Dirichlet $L$ -function $L (s, χ)$ and every $N \geq 2$ the Dirichlet series $L (s, χ) + L (2 s, χ) + \dots + L (N s, χ)$ have infinitely many zeros for $σ > 1$ .…

The converse of Bohr's equivalence theorem with Fourier exponents linearly independent over the rational numbers

M. Righetti, J. M. Sepulcre, T. Vidal

Given two arbitrary almost periodic functions with associated Fourier exponents which are linearly independent over the rational numbers, we prove that the existence of a common op…
