Abstract
A Feynman formula for the solving semigroup describing the evolution of the Wigner function (defined on the phase space of a finite-dimensional Hamiltonian system) is obtained. For an information concerning Feynman formulas, see V. A. Dubravina, Feynman formulas for solutions of evolution equations on ramified surfaces, Russ. J. Math. Phys. 21 (2), 285–288 (2014).
