Kruglikov, BorisAbstract
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.
It is rather close to the differential constraint method, but we make this rigorous basing on
recent advances in compatibility theory of non-linear overdetermined systems and homological
methods for PDEs.
