摘要

本文介绍了具有n个标记点的黎曼球紧化模空间上散射形式的性质。这些微分形式是$\text{PSL}(2，\mathbb{C})$不变的，它们的交点数对应于最近由Mizera提出的散射振幅。所有的奇点都在模空间的边界上，并且每个奇点都是对数的。此外，每个残差被分解成两种不同形式的最低点。

Properties of scattering forms for Yang-Mills amplitudes

In this talk we introduce the properties of scattering forms on the compactified moduli space of Riemann spheres with $n$ marked points. These differential forms are $\text{PSL}(2,\mathbb{C})$ invariant, their intersection numbers correspond to scattering amplitudes as recently proposed by Mizera. All singularities are at the boundary of the moduli space and each singularity is logarithmic. In addition, each residue factorizes into two differential forms of lower points.
