Wigner: a quantum phase-space probability function

What changed

Quantum states could be represented in phase space for equilibrium-correction calculations.

Scientific scope

Wigner's 1932 paper; later Weyl–Wigner–Moyal calculus and generalized quasidistributions excluded.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is Wigner’s exact 1932 paper and its equilibrium correction construction. Later Weyl–Wigner–Moyal formalism, generalized quasidistributions and applications remain separate.
