Maths HEP Lunchtime Seminars: Birkhoff's theorem in six-dimensional Gauss-Bonnet theory

Presented by Charalampos Bogdanos, Universite de Paris Sud-XI, Orsay

25 May 2009 13:00 in CM219

We discuss extensions of Birkhoff's theorem in the case of six-dimensional Gauss-Bonnet theory. Non-trivial constraints for the horizon geometry arise in this case, depending on the Weyl tensor of the internal space. We present exact solutions exhibiting staticity, even in the absence of spherical symmetry and give some examples of possible horizon geometries.
