SUMMARY:The Black Hole Threshold - David Hilditch\, IST Lisbon

DESCRIPTION: Numerical evolutions show that\, in spherical symmetry\, as w
 e move through the solution space of GR to the threshold of black hole for
 mation\, the resulting spacetimes tend to display a surprising degree of s
 implicity. A heuristic description of this behavior\, called critical coll
 apse\, has been built around this empirical fact. Less is known when symme
 try is dropped. In this presentation I will review the current status of t
 he topic\, focusing in particular on the struggle to understand the situat
 ion in axisymmetry.
