Résumé:

In this talk we will consider min-max minimal surfaces in three-manifolds and describe some related scalar curvature rigidity results. We will also mention some sharp estimates for the width in the case of positive Ricci curvature. The proofs use Ricci flow. This is joint work with Andre Neves.
