The authors demonstrate that the use of a spacetime transformation can greatly simplify the evaluation of the propagator for the problem of a particle with time-dependent mass, subject to a time-varying forced harmonic oscillator potential. They show that such a propagator can be easily obtained from the free propagator in the new spacetime coordinate system.
