Weyl relations determine the set of all physical quantities for a finite quantum theory, along operator on the GNS representation.13 But if T is a broken symmetry, ground states are not Leibniz equivalence entails that no spacetime symmetry transformation can relate physically The theorem of Halvorson and Clifton indicates that no spontaneously broken symmetry transformation can relate physically equivalent representations. Together with the physical possibility of broken spacetime symmetry, these criteria entail that states related by global rotations	./cache/work_xh4uzyqad5ayjnuqr3hvegkgua.pdf	./txt/work_xh4uzyqad5ayjnuqr3hvegkgua.txt
