论文摘要

我们表明,在对称组$ s_n $的作用下,具有$ n $标记点的稳定理性曲线的模量空间具有完整的特殊收集。特别是,其具有整数系数的K组是置换$ s_n $ lattice。

We show that the moduli space of stable rational curves with $n$ marked points has a full exceptional collection equivariant under the action of the symmetric group $S_n$ permuting the marked points. In particular, its K-group with integer coefficients is a permutation $S_n$-lattice.
