Let R be a ring and Q be a quiver. In this paper we give another definition of purity in the
category of quiver representations. Under such definition we prove that the class of all pure …

Source-finite infinite quivers were introduced recently by Enochs, Estrada, and García
Rozas. Their injective representations are characterized by local properties. Enochs et al …

We study bounded derived categories of the category of representations of infinite quivers
over a ring is a commutative noetherian ring with a dualising complex, we investigate an …

Let Λ be a non semisimple symmetric artin algebra over a commutative artinian ring R and
let repdim (Λ) be its representation dimension. Assume also that 𝒬 is a finite quiver whose …
