主积分的个数是有限的

The number of master integrals is finite

A. V. Smirnov, A. V. Petukhov

摘要:

对于一个固定的费曼图,我们可以考虑费曼积分与所有可能的传播子的幂,并试图减少他们,通过线性关系,到一个有限的积分子集,所谓的主积分。到目前为止,有许多例子减少程序导致有限数量的主积分的各种家庭的费曼积分。然而,到目前为止,这只是一个经验事实,约化过程的结果是有限个不可约积分。本文证明了主积分的个数总是有限的。

英文摘要:

For a fixed Feynman graph one can consider Feynman integrals with all possible powers of propagators and try to reduce them, by linear relations, to a finite subset of integrals, the so-called master integrals. Up to now, there are numerous examples of reduction procedures resulting in a finite number of master integrals for various families of Feynman integrals. However, up to now it was just an empirical fact that the reduction procedure results in a finite number of irreducible integrals. It this paper we prove that the number of master integrals is always finite.
