Project

Black-hole and radiative spacetimes exact methods (GA19-01850S)

The project aims to investigate black-hole and radiative spacetimes systems. The study of exact radiative spacetimes reveals the meaning of basic general properties of several such spacetimes: the Schwarzschild, Kerr and mo...
