I'm an Assistant Professor at the University of Virginia. My interests are geometric representation theory, knot homology and categorification.

comment Moment map of CP^1 as rational normal curve
You just multiply by n. Your direct calculation is wrong. I can't tell you anything more, since you don't reproduce it.

comment Reduction along an Orbit for C.-M. systems
@Brightsun It depends what you want to get out, of course. I don't think you necessarily need more symplectic geometry background, but Etingof's perspective is not one of pure symplectic geometry, so background in other areas like representation theory could also be useful. In terms of symplectic geometry, you might try some references that emphasize the Poisson side of things more, since that seemed to be what was throwing you off.

@DavidSpeyer pointed out that the same question was asked and answered by him on math.SE, so I've migrated so it can be closed.

comment If the Lie algebra is a direct sum, then the Lie group is a direct product?
I'm closing because the question is answered in comments.

comment Hall-Littlewood functions and functions on the nilpotent cone
I don't think you really mean the nilcone, as your construction of the line bundle doesn't make sense in this case (what's the fiber over 0? by your description, it should be $\mathbb{C}$ modulo a non-trivial action of the product of GL's, which isn't a line); these line bundles will only make sense on $T^*(SL_n/B)$. Of course, you might prefer to think about their pushforward to the nilcone, but that's emphatically not a line bundle.
