New symmetries from old: exploiting lie algebra structure to determine infinitesimal symmetries of differential equations
We give a method for using explicitly known Lie symmetries of a system of differential equations to help find more symmetries of the system. A Lie (or infinitesimal) symmetry of a system of differential equations is a transformation of its dependent and independent variables, depending on continuous...
