Stable manifolds of biholomorphisms in $\mathbb{C}^n$ asymptotic to formal curves

Abstract

Given a germ of biholomorphism $F\in\mathrm{Diff}(\mathbb{C}^n,0)$ with a formal invariant curve $\Gamma$ such that the multiplier of the restricted formal diffeomorphism $F|_\Gamma$ is a root of unity or satisfies $|(F|_\Gamma)'(0)|<1$, we prove that either $\Gamma$ is contained in the set of periodic points of $F$ or there exists a finite family of stable manifolds of $F$ where all the orbits are asymptotic to $\Gamma$ and whose union eventually contains every orbit asymptotic to $\Gamma$. This result generalizes to the case where $\Gamma$ is a formal periodic curve.
