摘要
We study composition operators on the Hardy space 7-12 of Dirich-let series with square summable coefficients. Our main result is a necessary condition, in terms of a Nevanlinna-type counting function, for a certain class of composition operators to be compact on 7-12. To do that we extend our no-tions to a Hardy space 7-12? of generalized Dirichlet series, induced in a natural way by a sequence of Beurling's primes.
