Hedgehogs in higher dimensions and their applications

Abstract

In this paper we study the dynamics of germs of holomorphic diffeomorphisms of $({\mathbb{C}}^n,0)$ with a fixed point at the origin with exactly one neutral eigenvalue. We prove that the map on any local center manifold of $0$ is quasiconformally conjugate to a holomorphic map and use this to transport results from one complex dimension to higher dimensions.
