Conservation Laws of Discrete Evolution Equations by Symmetries and Adjoint Symmetries
, 2015 A direct approach is proposed for constructing conservation laws of discrete evolution equations, regardless of the existence of a Lagrangian. The approach utilizes pairs of symmetries and adjoint symmetries, in which adjoint symmetries make up for the ...

Discrete derivatives and symmetries of difference equations
, 2001 We show with an example of the discrete heat equation that for any given discrete derivative we can construct a nontrivial Leibniz rule suitable for finding the symmetries of discrete equations.

Symmetry group analysis and invariant solutions of hydrodynamic-type systems
International Journal of Mathematics and Mathematical Sciences, 2004 We study point and higher symmetries of systems of the hydrodynamic type with and without an explicit dependence on t,x. We consider such systems which satisfy the existence conditions for an infinite-dimensional group of hydrodynamic symmetries which ...
