(for derek)

i want to try thinking outloud here a bit about the geometry of the conformal compactification of 2+1 space-time... because some of the ideas that came up during the discussion are bugging me a bit...

... something you mentioned about non-"reductiveness" of "parabolic geometries" ...

... also something about the shape of the generic region ... ???....
