Abstract

The present Thematic Project focuses on the context of Einstein's General Relativity, the physical and mathematical description of the spacetime and its associated phenomena. Its main research points can be grouped in the following topics: Fields in curved spacetimes and semi-classical gravitation, Geometric Aspects, Relativistic Astrophysics, and Analogue Models. Al these topics have been already considered by the working group. (AU)
