题目：Scalar curvature comparison and rigidity

报告人：姚萱 （Cornell University）

摘要：We introduced a new boundary comparison condition and proved a scalar curvature comparison and rigidity result. This can be seen as a smooth analog of Gromov's conjecture on polyhedron and a parallel of Shi-Tam's result on the positivity of the Brown-York mass.
