Description
An epsilon-factorised differential equation allows us to construct solutions for a given Feynman integral to all order in the dimensional regularisation parameter epsilon. The task of computing a Feynman integral is therefore reduced to finding a transformation, which puts the differential equation for a Feynman integral into an epsilon-factorised form. In this lecture I will show how such a transformation can be found for elliptic Feynman integrals and Calabi-Yau Feynman integrals.
