Stability of RCD condition under concentration topology
Abstract
We prove the stability of the Riemannian curvature dimension condition introduced by Ambrosio–Gigli–Savare under the concentration of metric measure spaces introduced by Gromov. This is an analogue of the result of Funano–Shioya for the curvature dimension condition of Lott–Villani and Sturm. These conditions are synthetic lower Ricci curvature bound for metric measure spaces. En route, we also prove the convergence of the Cheeger energy in our setting.
