IV.R296 — Abelianization and the torus projection
The abelianization F_2 -> Z x Z sends torus characters to lemniscate characters by forgetting loop ordering; the non-uniqueness of the lift is physical, corresponding to internal ordering of sub-processes within a quantum state, which measurement collapses.
