… The category of additive functors Cop −→ Ab is denoted by (… functors Cop −→ Ab, and we
observe that (Cop, Ab) is an abelian Grothendieck category. Our basic tools are the functors …

… with respect to the Ext and Tor functors. We also construct cotorsion pairs from these
orthogonal complements, allowing us to provide further characterizations of n-coherent rings. …

we will say that F is an exact functor if the exactness of the above sequence in implies the …
