摘要：
We study the relation between projective T-varieties and their affine cones in the language of the so-called divisorial fans and polyhedral divisors. As an application, we present the Grassmannian Grass(2, n) as a '' fansy divisor '' on the moduli space of stable, n-pointed, rational curves (M) over bar (0,n).(c) 2007 Elsevier B.V.
