Feynman图多项式的性质

Properties of Feynman graph polynomials

Christian Bogner

摘要:

在这个演讲中,我讨论的性质的两个Symanzik多项式,其中的被积函数的任意多圈积分在其费曼参数形式。基于生成森林和拉普拉斯矩阵的构造,应用Dodgson关系导出了涉及两个多项式的分解恒等式。讨论了Whitney的2-同构定理在拟阵上的一个应用。

英文摘要:

In this talk I discuss properties of the two Symanzik polynomials which characterise the integrand of an arbitrary multi-loop integral in its Feynman parametric form. Based on the construction from spanning forests and Laplacian matrices, Dodgson's relation is applied to derive factorisation identities involving both polynomials. An application of Whitney's 2-isomorphism theorem on matroids is discussed.
