A fansy divisor on M0,n
Klaus Altmann, Georg Hein
Abstract
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.
