Michele Valiante,Paola GrammaticoA close look at much of the earlier material, especially in the last chapter, reveals the strong connection between projectives and injectives. The idea is this: Formulate your result purely in terms of arrows (morphisms), then reverse them. That is, work in the opposite category. Not everything can be done this way, but a surprising amount can.

In this chapter, functors beyond Horn and ⊗ will be applied to projective (and injective) resolutions in .. In the next chapter, these constructions will be carried out in more general categories.
