Stephen McCormick: Gluing collars to manifolds; how and why
Time: Thu 2019-11-28 11.00 - 12.00
Participating: Stephen McCormick, Uppsala University
We review a procedure to glue together Riemannian manifolds with non-negative scalar curvature by first attaching a small "collar" to the manifold. We will then review some applications of this construction to problems related to the Bartnik mass and a geometric inequality in general relativity.
This is based on joint work with Armando Cabrera Pacheco, Carla Cederbaum, and Pengzi Miao.
