费曼图多项式

Feynman graph polynomials

Christian Bogner, Stefan Weinzierl

摘要:

任何多回路积分的被积函数在费曼参数化后由两个多项式表征。在这篇综述中,我们总结了这些多项式的性质。本文涉及的主题包括:生成树和生成森林,所有未成年人矩阵树定理,递归关系,由于收缩和删除的边缘,道奇森的身份和拟阵。

英文摘要:

The integrand of any multi-loop integral is characterised after Feynman parametrisation by two polynomials. In this review we summarise the properties of these polynomials. Topics covered in this article include among others: Spanning trees and spanning forests, the all-minors matrix-tree theorem, recursion relations due to contraction and deletion of edges, Dodgson's identity and matroids.
