论文摘要
这些笔记是2017年6月在Carma研讨会上发表的我演讲的书面版本，并提供了一些其他材料。我提出了一些最近在Compinatorics社区可能感兴趣的上下文中，这些概念最近被用于树级散射幅度的计算（主要是使用纯纺纱方法，但不限于它）。特别是，我专注于{\ it平面二进制树的外观}在散射幅度中，并提出了相关对象遵守的一些好奇的身份，其中一些仅通过显式示例已知是正确的。
These notes are a written version of my talk given at the CARMA workshop in June 2017, with some additional material. I presented a few concepts that have recently been used in the computation of tree-level scattering amplitudes (mostly using pure spinor methods but not restricted to it) in a context that could be of interest to the combinatorics community. In particular, I focused on the appearance of {\it planar binary trees} in scattering amplitudes and presented some curious identities obeyed by related objects, some of which are known to be true only via explicit examples.
