| May 28 at 16:56 | comment | added | Simon Henry | To precise Tim's Comment : pushout in the category $Pr^L$ are computed as pullback in Pr^R, which themselve are computed as pullback in Set. The "generaization" of this fact about $Pr^L$ would be a question about pullback of right adjoint functors instead. | |
| May 28 at 14:53 | comment | added | Tim Campion | The answer is presumably “no”. Even if it were “yes”, this would not be a generalization of the fact in $Pr^L$ because the forgetful functor $Pr^L \to Cat$ does not preserve pushouts. | |
