A classification of pure states on quantum spin chains satisfying the split property with on-site finite group symmetries
For pure split states on a quantum spin chain with an on-site finite group symmetry, the second cohomology class of the group is a complete invariant under the equivalence generated by symmetry-preserving asymptotically inner automorphisms.
