Abstract: | For internal symmetries it is shown that it is possible to construct automorphisms for a Haag-Araki local ring system {(O)} from a local current affiliated to it. Although the chargesQ
v
for finite volumeV do not converge forV we prove the convergence of the corresponding automorphisms of {(O)}. For external symmetries which map bounded space-time regions into unbounded ones (e.g. translations) we have to require some additional continuity condition on the isomorphisms corresponding toQ
v
to get convergence. |
