Z. Bendaoud, F. Korrichi, L. Merghni, A. Yagoub

• Let φ be a holomorphic self-map of the unit disc. We study the relationship between the generalized Nevanlinna counting function associated with φ and the norms of φn in the Dirichlet spaces. We give examples of Hilbert-Schmidt composition operators on the Dirichlet spaces.
