摘要：

We make a change of variables and a time reparametrization in the Schrodinger equation in order to obtain the propagator of a changed oscillator with a time-dependent mass and frequency under the influence of time-varying electric and magnetic fields, in terms of the simple propagators of harmonic oscillators with constant frequencies and masses. We also discuss the Jackiw transformation and others as a particular case of ours.
