We show that if a noncollapsed $C D (K, n)$ space $X$ with $n \geq 2$ has curvature bounded above by $κ$ in the sense of Alexandrov then $K \leq (n - 1) κ$ and $X$ is an Alexandrov space of…

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…
