Rigidity for the spectral gap on $R C D (K, \infty)$ -spaces

Nicola Gigli, Christian Ketterer, Kazumasa Kuwada +1

We consider a rigidity problem for the spectral gap of the Laplacian on an $R C D (K, \infty)$ -space (a metric measure space satisfying the Riemannian curvature-dimension condition) fo…

Sub-Laplacian comparison theorems on totally geodesic Riemannian foliations

Fabrice Baudoin, Erlend Grong, Kazumasa Kuwada +1

We develop a variational theory of geodesics for the canonical variation of the metric of a totally geodesic foliation. As a consequence, we obtain comparison theorems for the hori…
