on the global structure of spacetimes
abstract:
i will survey some known facts and open questions concerning the global properties of 3+1 dimensional spacetimes, with emphasis on the cauchy problem. according to the bkl proposal generic singularities with non-stiff matter are space-like and oscillatory while in the presence of stiff matter or scalar fields the singularity is quiescent. i will discuss the picture that emerges from the bkl proposal and review some recent results on nonlinear stability and the cauchy problem with rough initial data.
