| Jul 18, 2014 at 8:56 | comment | added | Jamie Vicary | @VictorOstrik: is it written down somewhere that these definitions are equivalent in this case, and that they imply the existence of a bona-fide 3d TQFT? | |
| Jul 17, 2014 at 19:24 | comment | added | Victor Ostrik | @JamieVicary: one definition would be that extension of scalars to algebraically closed field gives MTC. Another possibility is to require that Muger center is trivial. | |
| Jul 17, 2014 at 8:50 | comment | added | Jamie Vicary | @VictorOstrik: what is the definition of modularity by which these representation categories are MTCs? | |
