[Différentiabilité du profil isopérimétrique et topologie des variétés riemanniennes analytiques réelles]
On montre que la différentiabilité du profil isopérimétrique est une condition très contraignante pour les variétés riemanniennes analytiques réelles. Par exemple, sous une hypothèse supplémentaire, ce n'est possible que si la variété est homéomorphe à une sphère.
We show that smooth isoperimetric profiles are exceptional for real analytic Riemannian manifolds. For instance, under some extra assumptions, this can happen only on topological spheres.
