comment Moment maps and flat degenerations of toric varieties
In your example, the generic fiber is smooth. When the generic fiber is singular, would the moment polytope always stay constant in a flat degeneration over $\mathbb{A}^1$?

comment Global Affine Flag Variety and Affine Flag Variety
Thanks! Is there any references for your comment? Why the family being topologically trivial imply that we could correspond the $T-$fixed points? In the example in my question, a copy of $\mathbb{P}^1$ degenerates to two copies of $\mathbb{P}^1$ glued at a point.

comment Global Affine Flag Variety and Affine Flag Variety
Thanks! I know $Fl$ is topologically trivial, but I am not sure how to make use of that at the moment. As for your comment, what is $K$? Is $T$ the maximal torus in $G$?

comment Intersections of $B$ and $B^-$ orbits in the flag variety $G/B$
Thanks! Are you referring to this paper of Kleiman 'The Transversality of a General Translate', or another paper? How does this paper immediately imply that Richardson varieties are nice and have dimension $l(w_1) - l(w_2)$?
