Evolution equation for Wigner function for linear quantization
An arbitrary linear combination of the so-called tau-quantizations as integral transformations of classical symbol to quantum operator matrix is considered. The evolution equation for Wigner function is derived. In general case this equation depends on the characteristic function of quantization. The case of harmonic oscillator is considered for Weyl and Jordan quantizations.
