چکیده

Given a compact holomorphic fixed-point-free self-map, f , of the open unit ball of a Hilbert space, we show that the sequence of iterates, (fn), converges locally uniformly to a constant map ξ with ‖ξ‖ = 1. This extends results of Denjoy (1926), Wolff (1926), Hervé (1963) and MacCluer (1983). The result is false without the compactness assumption, nor is it true for all open balls of J∗-algebras.

A Generalized Version of the Earle-Hamilton Fixed Point Theorem for the Hilbert Ball

Let D be a bounded domain in a complex Banach space. According to the Earle-Hamilton fixed point theorem, if a holomorphic mapping F : D 7→ D maps D strictly into itself, then it has a unique fixed point and its iterates converge to this fixed point locally uniformly. Now let B be the open unit ball in a complex Hilbert space and let F : B 7→ B be holomorphic. We show that a similar conclusion ...

The Carathéodory-Cartan-Kaup-Wu theorem on an infinite-dimensional Hilbert space

This paper treats a holomorphic self-mapping f : Ω → Ω of a bounded domain Ω in a separable Hilbert space H with a fixed point p. In case the domain is convex, we prove an infinitedimensional version of the Cartan-Carathéodory-Kaup-Wu Theorem. This is basically a rigidity result in the vein of the uniqueness part of the classical Schwarz lemma. The main technique, inspired by an old idea of H. ...

Complexity of holomorphic maps from the complex unit ball to classical domains

We study the complexity of holomorphic isometries and proper maps from the complex unit ball to type IV classical domains. We investigate on degree estimates of holomorphic isometries and holomorphic maps with minimum target dimension. We also construct a real-parameter family of mutually inequivalent holomorphic isometries from the unit ball to type IV domains. We also provide examples of non-...
