Quillen equivalences for stable categories

Abstract

For an abelian category A\mathcal{A} we investigate when the stable categories GProj(A)\underline{\mathrm{GPro}}\mathrm{j}(\mathcal{A}) and GInj(A)\underline{\mathrm{GIn}}\mathrm{j}(\mathcal{A}) are triangulated equivalent. To this end, we realize these stable categories as homotopy categories of certain (non-trivial) model categories and give conditions on A\mathcal{A} that ensure the existence of a Quillen equivalence between the model categories in question. We also study when such a Quillen equivalence transfers from A\mathcal{A} to categories naturally associated to A\mathcal{A}, such as Ch(A)\mathrm{Ch}(\mathcal{A}), the category of chain complexes in A\mathcal{A}, or Rep(Q,A)\mathrm{Rep}(Q,\mathcal{A}), the category of A\mathcal{A}-valued representations of a quiver QQ.
