Besides the usual and well known Lie symmetries of the Schrodinger equation, the authors study higher-order symmetry operators and point out their impact on classes of solvable potentials when time-independent interactions take place for one-dimensional (space) systems. They consider the case of nth-order symmetry operators and more particularly the third-order context.
