### Lecture I: The shape of the space-time (Sommerfeld Theory Colloquium)

May 12, **16:00h (s.t.)**, A348/349, Theresienstr. 37

Abstract: In this talk, I shall go over the history of the geometry of spacetime according to general relativity and string theory.

### Lecture II: Quasilocal mass in general relativity (Munich Mathematical Colloquium)

May 13, **17:00h (s.t.)**, B052, Theresienstr. 39

Abstract: In this talk, I shall discuss a concept of mass, based on the theory of general relativity, for some compact region in spacetime that is due to M.T. Wang and myself. There are important properties of this mass that we shall discuss in this talk. There are interesting geometry and analysis behind the theory.
