Abstrakt: In this comment we evaluate Feynman's propagator exactly for a time-dependent quadratic Lagrangian, by solving the Schrödinger equation. Through a dilatation-rotation transformation, we show that such a propagator can be obtained from the free-particle propagator in a new space-time coordinate system. [ABSTRACT FROM AUTHOR]
