Seminario Dottorato 2021/22 - Alessandro Socionovo (15.06.2022)

We discuss the general notions of sub-Riemannian geometry. In particular, we study in parallel a toy sub-Riemannian model taken from real life and the general sub-Riemannian setting. In the final part of this talk, we introduce the open problem of the regularity of sub-Riemannian geodesics.
