The supersymmetric vistas of the supergravity landscape

In the recent times a lot of effort has been devoted to improve our knowledge about the space of string theory vacua (“the landscape”) in order to find statistical grounds to justify how and why the theory selects its vacuum. Particularly interesting are those vacua that preserve some supersymmetry, which are always supersymmetric solutions of some supergravity theory. We are going to review some recent results on the problem of finding all the supersymmetric solutions of a supergravity theory. We will also review some interesting solutions that have been discovered using these methods.
