Second order differentiation formula on $RCD(K,N)$ spaces

Analysis of PDEs 2018-07-18 v1

Abstract

We prove the second order differentiation formula along geodesics in finite-dimensional RCD(K,N)RCD(K,N) spaces. Our approach strongly relies on the approximation of W2W_2-geodesics by entropic interpolations and, in order to implement this approximation procedure, on the proof of new (even in the smooth setting) estimates for such interpolations.
