A Brief Review of Some Other Methods, star-triangle uniqueness relations [16, 23, 36] are methods for evaluating massless diagrams. The method of IR rearrangement [38], also in a generalized version based on the ..-operation [14, 34], is a method oriented at renormalization-group calculations.

Non-Stationary Intergenerational Altruismer integrals. In contrast to the evaluation of the master integrals, which is performed, at a sufficiently high level of complexity, in a Laurent expansion in ɛ, the reduction problem is solved at ., and the expansion in ɛ does not provide simplifications here.

Moreover, in contrast to other methods of evaluating individual Feynman integrals, it is assumed within this method that a solution of the reduction problem is already known.

The use of these parameters enables us to transform Feynman integrals over loop momenta into parametric integrals where Lorentz invariance becomes manifest. Using alpha parameters we shall first evalu

We shall, however, deal with a very specific technique in this field. The key ingredient of the method presented in this chapter is the MB representation used to replace a sum of two te
