Program Description:

The experimental detection of gravitational waves in 2015, achieved through the combined efforts of experimental physics, engineering, data science, and numerical analysis, has sparked renewed interest in their theoretical underpinnings. At the same time, increased precision in astronomical observations has revealed tensions that may challenge the standard cosmological paradigm, the ACDM model. These developments have renewed interest in examining the foundations of cosmology and the assumptions on which it rests. In particular, there is a pressing need to more fully understand and account of the  nonlinear behaviour of solutions to the Einstein equations.

This workshop focuses on the mathematical aspects of Einstein’s theory of gravity, general relativity. Our emphasis will be on developments that are related to the theory of gravitational waves and cosmology. This includes:

• the asymptotics of the gravitational field, in the context of the global non-linear evolution problem, both for isolated self-gravitating systems and in the cosmological setting;
• the study of Einstein–matter systems, in particular with regard to the study of emitted radiation, Newtonian and post-Newtonian approximations;
• advances in numerical simulations;
• and advances in scattering theory.

Researching gravity naturally draws from a range of disciplines. The aim of this workshop is to bring together researchers in pure mathematics, theoretical physics, and data science who are working on topics in mathematical general relativity related to gravitational waves.
