Linearly reducible Feynman integrals
Erik Panzer (Humboldt University)

In some cases, the representation of Feynman integrals in Schwinger parameters is simple enough such that it can be integrated directly in terms of multiple polylogarithms with available programs. I will summarize classes of graphs which belong to this class and explain the related criterion. Then I will sketch how specially adapted parametrizations extend this method, in a very efficient way, to infinite classes of 3- and 4-point functions.
