Webthe distribution functions obtained by the Weyl correspondence [4] are the Wigner functions. Moyal also showed how the time dependence of W and other such functions (which arise from alternative association rules other than Wigner-Weyl but which lead to the same physical results) may be determined without using the Schr¨odinger equation.
