Abstract
En 中文
Let n >= 1 and phi: D-n -> D be a holomorphic function, where D denotes the open unit disk of C. Let Theta : D -> D be an inner function and K-Theta(p), p> 0, denote the corresponding model space. We obtain characterizations of the compact composition operators C-phi: K-Theta(2) -> H-2(D-n), n >= 1, and C-phi : K-Theta(p) -> H-p(D-n), 1 p(D-n) denotes the Hardy space.
