Summer School »Between Geometry and Relativity« Mitschnitt einer Veranstaltung des Internationalen Erwin Schrödinger Instituts für Mathematik und Physik (ESI) am Freitag, dem 21. Juli 2017 im Lise Meitner-Hörsaal der Fakultät für Physik Teil 23: Richard Schoen: Positive Energy Theorems 9 Kamera: Raphael Wos, Viktor Zdrachal Schnitt: Daniel Winkler Abstract: We will introduce positive energy/mass problems in general relativity and discuss methods for solving some of them. The methods will involve minimal hypersurfaces and marginally outer trapped surfaces and require an understanding of existence problems as well as the second variation and stability notions for these hypersurfaces. We will also introduce Penrose inequalities which give stronger versions of positive energy theorems for black hole spacetimes. We will describe the flow approaches which have been developed to prove the Riemannian Penrose inequality. Richard Schoen ist Professor am Department of Mathematics der University of California.
