If you GIT quotient right then left, you get your space (or really, Deligne-Mostow's). If you GIT quotient left then right, you get the weight space interpretation I'm talking about.

| Feb 10, 2015 at 15:44 | comment | added | Michael Schuster | Thanks for your answer! About #2: What is the intuition behind looking at the multiplicity in $\vec{a}$ in $V_{s\omega_2}$? (I'm assuming $\omega_2$ is the second fundamental weight.) Is the formula the Verlinde formula or is it something else? A reference would be much appreciated! | |
