AIMR Math Group Seminar #16



Date : Feb. 8th (Fri.) 10:00~12:00

Place:3C, AIMR Main Bldg., Katahira campus, Tohoku University

SpeakerDr. Yohei Sakurai

Title : Characterization of lower curvature bounds



I talk about synthetic treatment of Riemannian curvatures. I present some characterization results of lower curvature bounds on smooth metric measure spaces which enable us to define the notion of lower curvature bounds for non-smooth metric measure spaces or discrete spaces. First, I will review celebrated characterization results on sectional and weighted Ricci curvature. After that, I will introduce my result concerning weighted Ricci curvature induced from an affine connection.
