Talk: Techniques in Conformal Lorentzian Geometry

Olaf Müller (U. Regensburg, Germany)

Tuesday 9, 12:45-13:45

In this talk I want to present some recent progress on different but related results around conformality in Lorentzian geometry. The first result yields a technique to derive global existence for initial values small in an appropriate Sobolev space for semilinear conformally invariant equations. The second result (which is work in progress) considers the causal boundary, which is a Lorentzian invariant, and connects it to the topological boundary of certain conformal embeddings.
