Black hole dynamics from a mathematical perspective — •Dejan Gajic — Institut für Theoretische Physik, Universität Leipzig, Brüderstraße 16, 04103 Leipzig

I will present an overview of recent mathematical results on the dynamics of spacetimes arising from initial data perturbations of Kerr black holes, both from linear and nonlinear point of view. An important role is played by extremal black holes, which exhibit novel dynamical features, such as instabilities and criticality.

Keywords: black hole; stability; instability; extremal; waves
