| Oct 13, 2009 at 6:20 | comment | added | Noah Snyder | I'm somewhat confused on one point, I thought that TQFTs coming from Turaev-Viro (in other words when the MTC is the Drinfel'd center of a semisimple spherical cateogry) didn't have an anomaly. But by your description they still see the 4-d structure because their total quantum dimension isn't 1. | |
