Hypertrees, projections, and moduli of stable rational curves (1004.2553v2)
Published 15 Apr 2010 in math.AG
Abstract: We give a conjectural description for the cone of effective divisors of the Grothendieck-Knudsen moduli space of stable rational curves with n marked points. Namely, we introduce new combinatorial structures called hypertrees and show they give exceptional divisors with many remarkable properties.
