Topology, Algebraic Geometry, and Dynamics Seminar (TADS): Metric invariants and scalar curvature
Apr 10, 2026, 1:30 - 2:30 PM
Speaker: Aditya Kumar, University of Maryland
Title: Metric invariants and scalar curvature
Abstract: We will discuss counterexamples to the macroscopic version of Gromov’s Urysohn width conjecture for scalar curvature in dimensions four and above. They are based on a novel estimate on the codimension-two Urysohn width of circle bundles over manifolds with large hypersphericity radius. This is based on joint work with Balarka Sen.
