Calculating Four-Loop Corrections in QCD,rs, with specific focus on deep-inelastic scattering and electron-positron annihilation. The calculations build on the parametric reduction of loop and phase space integrals up to four-loop order using computer algebra programs such as ., designed for large scale computations.

We first summarize the lessons learned from the study of the remainder functions of the 2 → 4 and the 2 → 5 scattering amplitudes and then present new results for the 2 → 6 amplitude.

Exkurs: Algebraische Strukturen,s of such systems. We will illustrate the methods developed in Dreyfus and Weil (Computing the Lie algebra of the differential Galois group: The reducible case, ArXiv . 2019) on several examples to reduce the differential system. This will give information on potential algebraic relations between integrals.
