Abstract:
We consider partial differential equations of a variational problem admitting
infinite-dimensional Lie symmetry algebras parameterized by arbitrary
functions of dependent variables and their derivatives. We show that unlike
differential systems with symmetry algebras parameterized by arbitrary
functions of independent variables, these equations have infinite sets of
essential conservation laws.
