Composition operators and generalized primes

Athanasios Kouroupis

We study composition operators on the Hardy space H2 of Dirichlet series with square summable coefficients. Our main result is a necessary condition, in terms of a Nev…

Composition operators on weighted Hilbert spaces of Dirichlet series

Athanasios Kouroupis, Karl-Mikael Perfekt

We study composition operators of characteristic zero on weighted Hilbert spaces of Dirichlet series. For this purpose we demonstrate the existence of weighted mean counting functi…
