We shall prove the following generalization of Ritt's theorem: every holomorphic self-map f: X →X such that f(X) is relatively compact in X has a unique fixed point τ(f) ∈ X, which is attracting. Furthermore, we shall prove that τ(f) depends holomorphically on f in a suitable sense, generalizing results by Heins, Joseph-Kwack and the second author.展开更多

文摘In this paper, we discuss the Valiron's theorem in the unit polydisk D^N. We prove that for a holomorphic map φ:D^N→D^N satisfying some regular conditions, there exists a holomorphic map θ:D^N→H and a constant α〉 0 such that θ°φ=1/αθ. It is based on the extension of Julia-Wolff-Caratheodory (JWC) theorem of D in the polydisk.
