| Mar 21, 2014 at 9:12 | comment | added | bananastack | I see. The answer should be no, as I don't think there's any reason to expect that in a dg-category a square is cartesian iff it is cocartesian. I'll see if it makes sense and if I can find a reference. | |
| Mar 21, 2014 at 5:28 | comment | added | Sasha | Thank you. But I asked a bit different question, I think: not whether the totality of pre-tri. dgcats model the same homotopy theory as stable cats, but whether a dgcat which, as an inf-cat, admits small colimits, is then automatically pre-tri. | |
