Webdiﬀerential constraints and Lagrange-Charpit method BorisKruglikov Abstract Many methods for reducing and simplifying diﬀerential equations are known. They provide various generalizations of the original symmetry approach of Sophus Lie. Plenty of relations between them have been noticed and in this note a unifying approach will be discussed.
