I would like to discuss our working progress on the epsilon form of differential equations for elliptic Feynman integrals. Frequently, two-loop Feynman integrals with several massive parameters are elliptic or even hyper-elliptic. In this case, the corresponding differential equation becomes very complicated. We combine the techniques of Picard-Fuchs equation, modular forms and maximal cut to find a simple form of elliptic differential equations.
