Shannon's inequality on non-collapsing RCD spaces

Metric Geometry 2024-11-08 v2

Abstract

We prove the Shannon's inequality on non-collapsing RCD(0,N)\mathsf{RCD}(0,N) spaces. In the proof, we use the characterization of the EVI0,N\mathsf{EVI}_{0,N}-gradient flow of the relative entropy and the infinitesimal behavior of the heat kernel. Also we have a cone rigidity result. As an application, we have the so-called uncertainty principle inequality on such spaces.
