General Relativity: Physics and Mathematics


A contribution by Peter C. Aichelburg and Piotr T. Chrusciel

The inaugural lecture of P. Chrusciel in January 2011 was entitled: "General relativity: Physics or Mathematics?" The above variant of this title provides a good description of the breakthrough progress in gravitational physics in spring 2017: the third detection of gravitational waves with LIGO.
