摘要
Recently Leach [Phys. Lett. A 158 (1991) 102] reported that Ermakov systems have the Lie algebra sl(2, R). Leach also reported the Lie algebra of the Ermakov-Lewis invariant to be sl(2, R). This is misleading and we complete his results. We also determine the general equation invariant under this new symmtery. Finally we find all (four) first integrals for Hamiltonian Ermakov systems.
