论文摘要
本文解释了如何使用量子场理论技术来查找编码$ \ mathrm {out}（f_n）$的虚拟欧拉特征和相关图形复合物的形式功率系列。在作者上一篇论文中进行的$χ（\ mathrm {out}（f_n））$χ（\ Mathrm {out}（f_n））的渐近分析中找到了这样的功率系列。
This paper explains how to use quantum field theory techniques to find formal power series that encode the virtual Euler characteristics of $\mathrm{Out}(F_n)$ and related graph complexes. Finding such power series was a necessary step in the asymptotic analysis of $χ(\mathrm{Out}(F_n))$ carried out in the authors' previous paper.
