Abstract :

Black holes are important objects of study in the theory of general relativity, and a natural question is what topologies they can have. In particular, can they have have more exotic shapes than spheres?

After giving an overview of how black holes are studied in mathematical general relativity, I will discuss a recent construction giving rise to many kinds of non-spherical black holes, as well as some earlier results which restrict the possible topologies.
