notes for discussion with huerta this evening...

??does the diffeomorphism preserve the fibers? or something...

??is the diffeomorphism as sugeested so far exactly correct in between the special points??

issue of whether "initial point" should explicitly appear in diffeomorphism formula...


??borel ideals and invariant distributions on flag variety...

??canonically identify pair (1d null subalg x of split octonions, point y of projective tangent space of x) with pair (x,f(x,y)) of 1d null subalgebras?? or something?? ....
