On Blow-Ups and Injectivity of Quivers

Abstract

This work connects the idea of a "blow-up" of a quiver with that of injectivity, showing that for a class of monic maps Φ\Phi, a quiver is Φ\Phi-injective if and only if all blow-ups of it are as well. This relationship is then used to characterize all quivers that are injective with respect to the natural embedding of PnP_{n} into CnC_{n}.
