Query: Equations for Chow and Hilbert Quotients   We give explicit equations for the Chow and Hilbert quotients of a projective
scheme X by the action of an algebraic torus T in an auxiliary toric variety.
As a consequence we provide GIT descriptions of these canonical quotients, and
obtain other GIT quotients of X by variation of GIT quotient. We apply these
results to find equations for the moduli space \bar{M}_{0,n} of stable genus
zero n-pointed curves as a subvariety of a smooth toric variety defined via
tropical methods.
