> 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).
