Abstract of Paper PLMS 1565
It is proved that the quantum stochastic gauge integral preserves self-adjointness of vacuum-adapted processes. This fact, together with bounded perturbations and the link between the Hudson--Parthasarathy calculus and vacuum-adapted theory, is used to produce many self-adjoint quantum semimartingales.
