> Title: Smooth and non-smooth aspects of Ricci curvature lower bounds.
>
> Abstract: After recalling the basic notions coming from differential
geometry, the talk will be focused on spaces satisfying Ricci curvature
lower bounds. The idea of compactifying the space of Riemannian manifolds
satisfying Ricci curvature lower bounds goes back to Gromov in the 80s and
was pushed by Cheeger and Colding in the 90s who investigated the fine
structure of possibly non-smooth limit spaces. A completely new approach
via optimal transportation was proposed by Sturm and Lott-Villani around
twenty years ago. Via such an approach one can give a precise definition of
what means for a non-smooth space to have Ricci curvature bounded below.
Such an approach has been refined in the last years giving new insights to
the theory and yielding applications which seems to be new even for smooth
Riemannian manifolds. The talk is meant to be an introduction to the topic,
accessible to non-specialists and as self-contained as possible.
