A Girsanov formula and an integration by parts formula are given for quantum stochastic processes on the Heisenberg-Weyl algebra and used to obtain sufficient conditions for their Wigner density in a given state to lie in the Sobolev space of order I;. 0 AcadCmie des SciencesElsevier, Paris Calcul d
AB ST R ACT. The classical results of stochastic calculus are extended to the equations giving the evolution of quantum observables in terms of their Weyl symbols, when the free Hamiltonian in ho(p) + qhl (p) or (t9 2/2m) + (rnco2/2)q z and the interaction potential is the Fourier transform of a bou
