Abstract
We study a two-loop four-point function with one internal mass. This Feynman integral is one of the simplest Feynman integrals depending on two elliptic curves. We transform the associated differential equation into an -form. We study the entries of the differential equation, and in particular the entries which depend on both elliptic curves.
