    The authors investigate relations between generalized Connes invariants of von Neumann algebras given by representations of invariant states of \(C^*\)-dynamical systems. The interesting results are then applied in the theory of local observables. It is shown that if a representation is connected with the vacuum by large translation then the wedge algebra is of type \(III_ 1\) under the condition that it is true for the vacuum representation.
