下面将详细描述two-loop recursion算法的步骤: 1.确定基本情况(Base Case): -在编写递归算法时,首先需要确定基本情况,即递归调用停止的条件。这可以是问题规模达到最小值或者某个特定条件满足时的情况。 2.划分子问题: -接下来,将原始问题划分为更小的子问题。这些子问题应该是原问题的简化版本,可以通过递归调用来...
Apart from having applications in thermal field theory, the integrals can be mapped onto one-loop three-point functions with collinear external momenta, suggesting the term "collinear" masses. We present a closed-form solution for these integrals, proving that they can always be factorized into ...
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 ...

we obtain the four recursion relations between the matrix elements of an arbitrary radial function, f(r), with the corresponding matrix elements of its first and second derivatives, taken between eigenstates of different potential functions, V 1 (r) and V 2 (r), with the corresponding ...
Finally all remaining integrals can be reduced by recursion [5] to bubble-integrals of the type V αβγ ({m}) = d d k 1 d d k 2 (k 2 1 −m 2 1 ) α (k 2 2 −m 2 2 ) β ((k 1 −k 2 ) 2 −m 2 3 ) γ , (6) or to factorizing one-loop integrals.Th...
Tail recursion works really well when the recursive step is last, but this algorithm has two recursive steps, so one of them is going to be not last, obviously. (Though as we'll see in a few episodes, there are things we can do about that.) Hmm. I just said ...
