Title: Mod R vs Mod RA_{\infty}^{\infty}

Abstract: The model theory of modules extends naturally to certain functor categories. One such category is that of representations of the biinfinite quiver A_{\infty}^{\infty}. For a fixed ring R, this raises the question of how the objects and morphisms of (model theoretic) interest for the category Mod RA_{\infty}^{\infty} relate to those of Mod R. In the simplest case, we take R to be von Neumann regular.
