Phys. Rev. A 42, 3733–3743 (1990)Path-integral derivation of phase-space distributionsReceived 3 January 1990; published in the issue dated October 1990 A functional P[γ] is defined on the space of histories for a quantum particle, and its meaning as a quasiprobability is discussed. The method of obtaining the Wigner and the Margenau-Hill phase-space distributions is shown as particular path integrals over P[γ]. © 1990 The American Physical Society URL:
