DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BOWL/12/">Sc
 alar curvature on aspherical manifolds</a>\nby Chao Li (Princeton) as part
  of B.O.W.L Geometry Seminar\n\n\nAbstract\nIt has been a classical questi
 on which manifolds admit Riemannian metrics with positive scalar curvature
 . I will first review some history of this question\, and present some rec
 ent progress\, ruling out positive scalar curvature on closed aspherical m
 anifolds of dimensions 4 and 5 (as conjectured by Schoen-Yau and by Gromov
 ). I will also discuss some related questions including the Urysohn width 
 inequalities on manifolds with scalar curvature lower bounds. This talk is
  based on joint work with Otis Chodosh.\n
