Limits of zeroes of holomorphic differential on stable nodal Riemann surfaces
Apparaît également dans la collection : Dynamics and geometry in the Teichmüller space / Dynamique et géométrie dans l'espace de Teichmüller
We discuss the current status of the problem of understanding the closures of the strata of curves together with a differential with a prescribed configuration of zeroes, in the Deligne-Mumford moduli space of stable curves.
