The existence of black holes is perhaps the most spectacular theoretical prediction of Einstein’s theory of general relativity. Quite remarkably, black holes are fundamentally simple objects, as they are completely described by their mass, angular momentum, and charge. Maximally spinning (or charged) black holes are known as extremal black holes. Unlike sub-extremal black holes, extremal (and near-extremal) black holes have remained largely unexplored because of their numerous intricacies. In view of the most recent advances in understanding sub-extremal black holes, a more thorough study of extremal and near-extremal black holes now appears as a natural and promising direction for important future developments in the subject. The workshop aims at presenting two perspectives on extremal black holes, namely their symmetries and dynamics, via the combination of ideas from physics, mathematics, and numerical simulations.
