comment Interesting behaviour of Brion's formula under a degenerate change of variables
I actually have been interested in very similar (perhaps the same) question some years ago. I think I can give an algebro-geometric (not combinatorial) argument for why the vertices that are not mapped to the vertices of $\phi(P)$ do not appear in the formula, at least for the case of $P =$ a Gelfand-Zetlin polytope. I would be very much interested to know if you have a combinatorial argument in this case.

comment Fubini-Study metric for an infinite dimensional Hilbert space
Thanks Ahmed and Alvarez, so definition works as in the finite dimensional case.
