Toric Degenerations of GIT Quotients, Chow Quotients, and $\bar{M_{0,n}$
Yi Hu
We show that the moduli space of stable n-pointed rational curves can be flatly degenerated to a projective toric variety. We arrive at this by showing that the Chow quotients of t…

Quotients by Reductive Group, Borel Subgroup, Unipotent Group and Maximal Torus
Yi Hu
Consider an algebraic action of a connected complex reductive algebraic group on a complex polarized projective variety. In this paper, we first introduce the nilpotent quotient, t…
