The injective fibrations are then defined as those maps which have the RIGHT-lifting property with respect to all cofibrations which are also weak equivalences.

| Dec 21, 2009 at 21:23 | comment | added | Chris Schommer-Pries | I know that the identity functor is a Quillen equivalence between these two model structures, and when C is Reedy the identity functor is also a Quillen equivalence with the Reedy model structure. So what I'm asking is definitely specific to the injective model structure. I don't want to replace it with an equivalent one. | |
