Dihedral Rigidity, Fill-in and Spacetime Positive Mass Theorem

Watch a General Relativity Workshop lecture exploring the relationship between scalar curvature and boundary geometry in compact manifolds, delivered by UC Irvine's Tin-Yau Tsang. Examine Gromov's proposed dihedral rigidity conjecture and fill-in conjecture, with particular focus on how the spacetime positive mass theorem helps address questions related to initial data sets. Gain insights into advanced mathematical concepts at the intersection of differential geometry and general relativity through this detailed 71-minute presentation from the Harvard CMSA series.
