Geometric Analysis and Mathematical Relativity Seminar —— A splitting theorem for scalar curvature

2018-05-24 14:30-16:30 Room 1556, Science building No.1 I'll discuss recent work with M. Eichmair and V. Moraru where we prove that a complete 3-manifold with non-negative scalar curvature that admits an absolutely area minimizing cylinder must be flat. This (essentially) completes the classification of area minimizing surfaces in the presence of non-negative scalar curvature.
