Notes on flag varieties and Grassmannians for beginners
Thanks all for the helpful references. I already knew some of them but definitely the comments and replies helped. |

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. |
