摘要:我们对具有\(n\)个标记点的稳定有理曲线的格罗滕迪克 - 克努森模空间\(\overline{M}_{0,n}\)的有效除子锥给出一个推测性的描述。即,我们引入称为超树的新组合结构,并表明它们在\(\overline{M}_{0,n}\)上给出具有许多显著性质的特殊除子。
Abstract We give a conjectural description for the cone of effective divisors of the Grothendieck–Knudsen moduli space M̅0,n of stable rational curves with n marked points. Namely, we introduce new combinatorial structures called hypertrees and show that they give exceptional divisors on M̅0,n with many remarkable properties.
