Abstract

This is a continuation of the study of the theory of quantum stochastic dilation of completely positive semigroups on a von Neumann or CC^* algebra, here with unbounded generators. The additional assumption of symmetry with respect to a semifinite trace allows the use of the Hilbert space techniques, while the covariance gives rise to better handle on domains. An Evans-Hudson flow is obtained, dilating the given semigroup.
