Rectifiability of RCD(K,N) spaces via $\delta$-splitting maps

Metric Geometry 2020-01-23 v1

Abstract

In this note we give new proofs of rectifiability of RCD(K,N) spaces as metric measure spaces and lower semicontinuity of the essential dimension, via δ\delta-splitting maps. The arguments are inspired by the Cheeger-Colding theory for Ricci limits and rely on the second order differential calculus developed by Gigli and on the convergence and stability results by Ambrosio-Honda.
