Colloquium: Gromov's Simplicial Volume Vanishing Conjecture
Speaker: Qiaochu Ma, Texas A&M University
Abstract: Gromov’s simplicial volume vanishing conjecture predicts that if a closed oriented manifold admits a positive scalar curvature metric, then its simplicial volume vanishes. In this talk, we present a proof of this conjecture, based on a quantitative refinement of the Connes-Moscovici higher index theorem. This is joint work with Jinmin Wang, Zhizhang Xie, Guoliang Yu, and Bo Zhu.
