| Nov 17, 2019 at 12:12 | comment | added | Valery Isaev | After some thought, I can solve the second problem I mentioned if the domains of generating cofibrations are cofibrant. Do you know how to do this in general? Also, the first problem is easy to solve. Weak equivalences actually do form an accessible subcategory. The rest of the proof seems to work just fine if we assume that a transfinite composition of pushouts of maps in $\mathrm{cof}(I) \cap \mathcal{W}$ is a weak equivalence as long as it has cofibrant domain. Is this correct? | |
