报告摘要:In this talk, we'll consider the non-negative scalar curvature (NNSC) fill-in and cobordism problem and mainly give some non existence results. Roughly speaking, suppose the Bartnik data satisfies and , then it admits no NNSC fill-in provided the mean curvature H is sufficiently large.  Similaly, suppose two triples of Bartnik data , satisfies , i=1,2, and is fixed, then they adimit no NNSC cobordism provided the mean curvature is sufficiently large.
