Second variation in general relativity

Monday 17th October 2005 - 16:00 to 17:00
INI Seminar Room 1

The formula for the second variation of area of a hypersurface is well known in geometry, where it is used to study stability questions involving minimal surfaces. It is not so well known is that it plays a key role in several seemingly unrelated classical computations in general relativity. I'll describe some of these applications.
