Jan 22, 2019 at 22:09 | comment | added | Liam Keenan | How is it that tensoring with B preserves monomorphisms? | |
Jan 15, 2019 at 15:13 | comment | added | Dmitri Pavlov | The intended use of monomorphisms is that monomorphisms in this case are h-cofibrations, which under left properness implies that a cobase change along such a map is also a homotopy cobase change, in particular, it preserves weak equivalences. Thus, in the resulting cube diagram three parallel maps are weak equivalences, hence so is the fourth one. | |
Jan 15, 2019 at 5:55 | comment | added | Liam Keenan | I don't know how you are using the preservation of monomorphisms. Could you elaborate on this? I have been trying to use the cube diagram obtained from the unit map, along with Hirschorn Prop. 17.9.2, to conclude the original $\eta_{M}$ is a weak equivalence. | |
