Examples of internal symmetries that are interior include gauge transformations which coincide with the identity on a neighbourhood of the boundary same possible world, such a subsystem transformation does not lead to a distinct situation, hence no (nontrivial) empirical symmetry is associated with such way for a subsystem symmetry σS to be boundary-preserving on all states is 3. Non-interior symmetries that are not boundary-preserving on the subsystem states of interest can have direct empirical significance, but, in boundary of W , then it defines a gauge transformation which is an interior symmetry of the subsystem: it is the restriction to the subsystem of the universe According to the general theory of empirical symmetries developed in sections 3 and 5, this means that 'local' subsystem gauge transformations that are	./cache/work_zgvz3qr7ubeablvj6hkcpf2zt4.pdf	./txt/work_zgvz3qr7ubeablvj6hkcpf2zt4.txt
