"From rough space-time to black holes.

                   Evolution problem in General Relativity"

by

Igor Rodnianski

Princeton

 

Abstract:
 I will start by explaining basic principles of General Relativity.

I will review the all familiar Einstein-vacuum space-times: Minkowski and

Schwarzschild, the latter giving the simplest example of a black hole

space-time, describe basic monotonicity property of the Einstein equations

and its use in the Penrose incompleteness theorem. I will then discuss the

evolution problem in General Relativity, explain how to construct rough

space-times and trapped surfaces, and explore several stability problems,

including that of black holes.  In that context I will examine global

behavior of linear waves and explain the role of the celebrated red-shift effect.
