Einstein spaces as attractors for the Einstein flow
Prof. Lars Andersson (AEI)
26 Jun 2007, 16:00 – 17:00

I will discuss a proof of nonlinear stability of Lorentz cones over Riemannian negative Einstein spaces. For higher dimensional Einstein spaces, there may be a nontrivial moduli space of Einstein structures, which may be viewed as a center manifold for the flow. I will discuss conditions for stability and give examples where they are satisfied. Under the condition that the spacetime dimension is at least 11, this work allows one to construct families of vacuum spacetimes with quiescent singularity and asymptotically Friedman behavior in the expanding direction.
