We present an exact solution for the two-dimensional chiral fields with multivalued action, and consider the relation of this theory to the CP-asymmetric Thirring model, free fermions, surrent algebras and Heisenberg antiferromagnets. Also, the parity violating lagrangian for the n-fields based on the Hopf topological invariant is briefly discussed.
