Feynman integrals with hyperlogarithms — •Erik Panzer — Humboldt-Universität zu Berlin, Deutschland

The classic theory of hyperlogarithms provides a versatile tool for the computation of some Feynman diagrams. We will report on the current status of this approach and in particular address the question of linear reducibility which is a necessary requirement for applying this method. Apart from examples of non-trivial integrals that can be calculated this way, we analyse counterexamples and possibilities to restore linear reducibility.
