Query: Restrictions of CP-Semigroups to Maximal Commutative Subalgebras   We give a necessary and sufficient criterion when a normal CP-map on a von
Neumann algebra admits a restriction to a maximal commutative subalgebra. We
apply this result to give a far reaching generalization of Rebolledo's
sufficient criterion for the Lindblad generator of a Markov semigroup on B(G).
