Course description:

General relativity is a rich interplay between geometry, analysis and physics. Methods of geometric analysis have proven to be most effective to investigate these structures. This course will start with an introduction into the Cauchy problem in general relativity. Then it will cover null hypersurfaces in Lorentzian spacetimes, establishing the geometric tools to investigate gravitational radiation. After that, I will discuss the nonlinear memory effect of gravitational waves. We will discuss D. Christodoulou's pioneering article of 1991 as well as new results of 2010 and 2011 co-authored by L. Bieri, P. Chen, S.-T. Yau for the case when electromagnetic fields are present.



Knowledge in Riemannian geometry and partial differential equations.
