Parabolic curves of diffeomorphisms asymptotic to formal invariant curves

Abstract

We prove that if $F$ is a tangent to the identity diffeomorphism at $0\in {\mathbb{C}}^2$ and $\Gamma$ is a formal invariant curve of $F$ then there exists a parabolic curve (attracting or repelling) of $F$ asymptotic to $\Gamma$. The result is a consequence of a more general one in arbitrary dimension, where we prove the existence of parabolic curves of a tangent to the identity diffeomorphism $F$ at $0\in {\mathbb{C}}^n$ asymptotic to a given formal invariant curve under some additional conditions, expressed in terms of a reduction of $F$ to a special normal form by means of blow-ups and ramifications along the formal curve.
