Finite cycles of indecomposable modules
Piotr Malicki, José Antonio de la Peña, Andrzej Skowroński
We solve a long standing open problem concerning the structure of finite cycles in the category mod A of finitely generated modules over an arbitrary artin algebra A, that is, the…
Cycle-finite module categories
Piotr Malicki, José A. de la Peña, Andrzej Skowroński
We describe the structure of module categories of finite dimensional algebras over an algebraically closed field for which the cycles of nonzero nonisomorphisms between indecomposa…
Covering functors without groups
Jose Antonio de la Peña, Maria Julia Redondo
Coverings in the representation theory of algebras were introduced for the Auslander-Reiten quiver of a representation finite algebra by Riedtmann and later for finite dimensional…
