Description
The calculation of Feynman Integrals is one of bottlenecks for precision calculations at Next-to-Next-to-leading order and beyond. Differential Equations have proven to be a powerful tool to relieve this bottleneck and have seen a rapid development in the last years. In this talk I will review these recent developments especially focusing on the so-called canonical form. I will present the Magnus algorithm as a tool to find these special forms. The presented techniques are then applied to several analytic calculations including part of the integrals relevant for Higgs+Jet production at three loops and for top pair production at two-loops.
