We show that almost split sequences in the category of comodules over a coalgebra Î“ with finite-dimensional right-hand term are direct limits of almost split sequences over finite dimensionalâ€¦ (More)

This paper studies connections between the preprojective representations of a valued quiver, the (+)-admissible sequences of vertices, and the Weyl group by associating to each preprojectiveâ€¦ (More)

The following are equivalent for a skeletally small abelian Homfinite category over a field with enough injectives and each simple object being an epimorphic image of a projective object of finiteâ€¦ (More)

Autologous engineered skin substitutes (ESS) containing melanocytes (hM) may restore pigmentation and photoprotection after grafting to full-thickness skin wounds. In this study, normal hM wereâ€¦ (More)

This paper studies connections between the preprojective modules over the path algebra of a finite connected quiver without oriented cycles, the (+)-admissible sequences of vertices, and the Weylâ€¦ (More)

Let Î› be an associative ring with identity and with the Jacobson radical r, let modÎ› be the category of finitely generated left Î›-modules, and let Î› be the opposite ring of Î›. All modules are leftâ€¦ (More)
