Abstract:In this paper we give a Carleson measure characterization for the compact composition operators between Dirichlet type spaces. We use this characterization to show that every compact composition operator on Dirichlet type spaces is compact on the Bloch space.
Keywords:Bergman spaces  Bloch space  Carleson measure  composition operators  Dirichlet type spaces
