Commutation of projections and trace characterization on von Neumann algebras. IIWe obtain new necessary and sufficient commutation conditions for
projections in terms of
operator Projection-operator determination of kinetic equations for a system of many particlesThe
projection-operator method worked out in general form by Nakajima and Zwanzig is used

operator in H. If U = P − Q is an isometry then U = U* is unitary and Q = I
