> Title: The neighborhood of a leaf of a singular foliation
> Abstract
>
>
> Near a leaf, regular foliations are classified by their monodromies. What
> about the singular leaves of singular foliations ? The first point is
> that for a singular leaf, there is a transverse singular foliation, which
> is constant all along the leaf. In a previous work, Leonid Ryvkin and I
> have proven that for simply connected singular leaves with a certain type
> of transverse singular foliations, there is only one possiblity: the
> direct product. Here, we present a complete classification at the formal
> level, which is composed of two parts: a sort of monodromy and a finite
> dimensional principal bundle. We use a presentation where Yang-Mills
> bundles (as introduced by Kotov and Strobl) play a central role. Joint
> work with Simon Raphael Fischer (Taipei).
