    Woops, that’s an embarrassing mistake of mine. Thanks for correcting this.

  1. The low-energy TQFT of the Walker-Wang model is expected to be the Crane-Yetter model, not the Yetter model: see

    Thanks Arun.

    It would be good if someone in the know could say something more about the relationship. The MO question has Walker say in response:

    the Walker-Wang model is related to the Crane-Yetter-Kauffman TQFT in the same way the Levin-Wen model is related to the Turaev-Viro TQFT.

    So this is the difference between state sum/partition function and Hamiltonian approaches, it seems. I can add that at least.
