Non-Classical Symmetry Analysis of a Class of Nonlinear Lattice Equations
In this paper, a non-classical symmetry method for obtaining the symmetries of differential–difference equations is proposed. The non-classical symmetry method introduces an additional constraint known as the invariant surface condition, which is applied after the infinitesimal transformation. By so...
