On the Mahler measure of the Coxeter polynomials of algebras
José-Antonio de la Peña
Let be a finite dimensional algebra over an algebraically closed field . Assume is a basic connected and triangular algebra with pairwise non-isomorphic simple modul…
Algebras whose Coxeter polynomials are products of cyclotomic polynomials
Jose-Antonio de la Peña
Let A be a finite dimensional algebra over an algebraically closed field k. Assume A is basic connected with n pairwise non-isomorphic simplemodules. We consider the Coxeter transf…
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…
