| Descripción: | Applying the Sarlet-Bahar method one obtains the invariant of equations of motion of the type <img src="../../../../../img/revistas/rmf/v53n1/a1s1.jpg">+ ω²(t)ρ/2 = α(t)F(β(t)ρ). The corresponding auxiliary equation for the Ermakov system is also obtained, and the results obtained by other authors are generalized. |
