Overview

This Brief presents in a self-contained, non-technical and illustrative fashion the state-of-the-art results and techniques for the dynamics of extremal black holes. Extremal black holes are, roughly speaking, either maximally rotating or maximally charged. Astronomical observations suggest that near-extremal (stellar or supermassive) black holes are ubiquitous in the universe. The book presents various recently discovered characteristic phenomena (such as the horizon instability) that have enhanced our understanding of the dynamics of extremal black holes. The topics should be of interest to pure mathematicians, theoretical physicists and astronomers. This book provides common ground for communication between these scientific communities.

Reviews

Very attractive feature of the book are the copious figures which greatly aid understanding. ... This book will be very useful for beginning graduate students who need to then study the proofs in the primary literature, as well as for researchers who wish to learn about the subject and understand the gist of the proofs without working through all the details. (Elizabeth Winstanley, zbMath 1419.83002, 2019)
