Abstract

We prove that if FF is a tangent to the identity diffeomorphism at 0C20\in\mathbb{C}^2 and Γ\Gamma is a formal invariant curve of FF then there exists a parabolic curve (attracting or repelling) of FF asymptotic to Γ\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 FF at 0Cn0\in\mathbb{C}^n asymptotic to a given formal invariant curve under some additional conditions, expressed in terms of a reduction of FF to a special normal form by means of blow-ups and ramifications along the formal curve.
