Foundations of phase-space quantum mechanics
Can one reexpress quantum-mechanical mean values as classical averages over phase-space distribution functions? Due to Wigner, such distribution functions, in general, cannot be non-negative. The ''stochastic phase space scheme'' is based on the observation that the concept of the ordinary phase space, as consisting of sharp points, is meaningless from the experimental point of view. Thus ''point'' has to be identified with the mean position and momentum of a particle.
