Uniform sub-Laplacian comparison theorems on Sasakian manifolds
Apparaît dans la collection : Journée sous-riemannienne 2018
We will discuss sharp estimates for the sub-Laplacian of a family of distances converging to the sub-Riemannian one. We will deduce results for the sub-Riemannian distance. Uniform measure contraction properties will also be discussed. This is joint work with Erlend Grong, Kazumasa Kuwada and Anton Thalmaier.
