算法概述 在介绍two-loop recursion算法之前,首先需要了解递归的基本概念。递归是一种通过调用自身来解决问题的方法。而two-looprecursion算法是在递归的基础上进行改进,通过引入两个循环来提高效率和性能。 递归的原理 递归是一种在函数中调用自身的编程技巧。它通过将复杂问题分解为更小的子问题来解决。每次递归调用都...
2 Massive two-loop vacuum integrals: IBP recursions For the massive two-loop scalar vacuum integrals Bν1,ν2,ν3(d; m21, m22, m23) that were defined in eq. (1.3), general results in terms of Appell's hypergeometric function F4 can be found1 in eq. (4.3) of [7]. As has ...
