Аннотация:
Non-Abelian (NA) version of the hierarchical FQH states is proposed. The topological order (TO) in these states is shown to be described by some U(N) coset Chern-Simons (CS) theory. For this all the necessary information about the TO can be found in the theory of the edge excitations (EE). This theory is described in terms of the corresponding gauged Wess-Zumino-Witten model related to the bulk theory through the Witten isomorfism.
