<description>
<string language="fre"><![CDATA[The theory of non smooth
spaces with lower Ricci Curvature bounds has undergone huge 
developments in the last thirty years. On the one hand the impetus came 
from Gromov’s precompactness theorem and the Cheeger-Colding theory of 
Ricci limit spaces. On the other hand “synthetic” theories of lower 
Ricci bounds have been developed, based on semigroup tools (the 
Bakry-Émery theory) and on Optimal Transport (the Lott-Sturm-Villani 
theory).
The Cheeger-Colding theory did not consider manifolds 
with boundary, while in the synthetic framework even understanding what 
is a good definition of boundary is a challenge. 
The aim of this 
talk is to present some recent results obtained in collaboration with E.
Bruè (IAS, Princeton) and A. Naber (Northwestern University) about 
regularity and stability for boundaries of spaces with lower Ricci 
Curvature bounds.]]></string></description>
