Description
The wave packet solution of the time-dependent Schroedinger equation for the harmonic oscillator with time-dependent frequency yields a coupled pair of equations of motion for the mean value and uncertainty of position which corresponds to an exact dynamical invariant. Its relation to the corresponding time-dependent Wigner function will be shown
