»Scalar curvature on open 3-manifolds «

Abstract:
Thanks to the geometrization conjecture the topological structure of compact 3-manifold is well known. Now we attempt to generalize it to open 3-manifolds. However, the topological structure of open 3-manifolds is more complicated. For example, the prime decomposition theorem cannot be generalized to open 3-manifolds. We will present a survey of results on open 3-manifold with (uniformly) positive scalar curvature. There are two methods which have enabled many breakthroughs: Ricci flow and Minimal hypersurfaces. In the talk, we will compare these two methods and explain how to get a prime decomposition of open 3-manifolds with uniformly positive scalar curvature. --------------------------------------- This is an online seminar.
