Abstract: Black holes are fundamental objects in our understanding of the universe. The mathematics behind them has surprising geometric properties, and their dynamics is governed by hyperbolic PDEs. A basic question one may ask is whether these solutions to the Einstein equation are stable under small perturbations, which is a typical requirement to be physically meaningful. We will see how the dispersion of gravitational waves plays a key role in the stability problem, illustrating the main conjectures and some recent theorems regarding the evolution of black holes and their interaction with matter fields.
