Abstract: We first describe the local and global moduli spaces of germs of foliations defined by analytic functions in two variables with $p$ transverse smooth branches, and with integral multiplicities (in the univalued holomorphic case) or complex multiplicities (in the multivalued “Darboux” case). We specify normal forms in each class. Then we study on these moduli space the distribution $\mathcal C$ induced by the following equivalence relation: two points are equivalent if and only if the corresponding foliations have the same analytic invariant curves up to analytical conjugacy. Therefore, the space of leaves of $\mathcal C$ is the moduli space of curves. We prove that $\mathcal C$ is rationally integrable. These rational integrals give a complete system of invariants for these generic plane curves, which extend the well-known cross-ratios between branches.
Key words and phrases: holomorphic foliation, moduli of curve, singularities.
