A note on lower bounds estimates for the Neumann eigenvalues of manifolds with positive Ricci curvature
Fabrice Baudoin, Alice Vatamanelu
We study new heat kernel estimates for the Neumann heat kernel on a compact manifold with positive Ricci curvature and convex boundary. As a consequence, we obtain new lower bounds…

A sub-Riemannian curvature-dimension inequality, volume doubling property and the Poincaré inequality
Fabrice Baudoin, Michel Bonnefont, Nicola Garofalo
Let be a smooth connected manifold endowed with a smooth measure and a smooth locally subelliptic diffusion operator satisfying , and which is symmetric…
