Abstract:Scalar curvature exhibits several rigidity properties, for instance, the positive mass theorem, the Geroch conjecture, and the more recent Gromov dihedral rigidity. In 1998, Llarull established a rigidity result for metrics on the round sphere under scalar curvature and metric comparison. In this talk, I report on recent progress toward understanding scalar curvature rigid domains and generalize Llarull type result in a warped product, where the warping function satisfies a log-concavity condition. This talk is based on joint works with Gaoming Wang (YMSC, Beijing) and Xueyuan Wan (CQUT, Chongqing).
