| Feb 4, 2010 at 3:44 | comment | added | Tom Leinster | Yeah, 2's kinda OK, probably. At least, it's not socially controversial. Though if you really want to know whether two notions of 2-category are the same, you have to compare the 3-categories that they form --- and there your headache begins... | |
| Feb 3, 2010 at 4:37 | comment | added | Daniel Moskovich | I think for weak 2-categories we are basically OK though, no? So this question, at least, should be relatively unambiguous (I hope!) although it might have multiple answers... | |
| Feb 3, 2010 at 2:44 | comment | added | Tom Leinster | It's worth sounding a note of caution here. Whenever anyone says that any statement involving the term "n-category" has been "proved", there's a caveat: it's far from clear what exactly "n-category" should mean. Many definitions have been proposed (including the one that Lurie uses), but there are thoroughly nontrivial outstanding questions about the relationships between them. So when a statement is proved using one proposed definition, it doesn't instantly follow that the statement is true for any of the other proposed definitions. | |
