Nonlocal symmetries and formal symmetries for evolution equations
Original language description
We consider the nonlocal symmetries associated with the universal Abelian coverings over (1+1)-dimensional evolution systems with constraints. We show that the directional derivatives of these symmetries are formal symmetries for the systems in question,thus generalizing similar results concerning local symmetries. Some related results are also presented.
