Local Poincaré inequalities in metric spaces with Ricci-curvature bounded from below 
Tapio Rajala (Scuola Normale Superiore and University of Jyväskylä)

Abstract. We discuss the definitions given by Lott and Villani and by Sturm of lower Ricci-curvature bounds in metric spaces via mass transportation. We show how local Poincaré inequalities can be obtained from these lower bounds. Previously such results were known to be true only under the extra assumption that the space is non-branching.
