A partial classification of simple regular representations of bimodules type over
Hernán Giraldo, David Reynoso-Mercado, Pedro Rizzo
In this paper, we use Galois descent techniques to find suitable representatives of the regular simple representations of the species of type over $k_n := k[\varepsilon^{1/…

String and band complexes over SAG algebras
Andrés Franco, Hernán Giraldo, Pedro Rizzo
We give a combinatorial description of a family of indecomposable objects in the bounded derived categories of a new class of algebras: string almost gentle algebras. These indecom…
Derived tame Nakayama algebras
Viktor Bekkert, Hernan Giraldo, Jose A. Velez-Marulanda
We determine the derived representation type of Nakayama algebras and prove that a derived tame Nakayama algebra without simple projective module is gentle or derived equivalent to…

Differential Galois Groups and Representation of Quivers for Seismic Models with Constant Hessian of Square of Slowness
Primitivo Acosta-Humánez, Hernán Giraldo, Carlos Piedrahita
The trajectory of energy is modeled by the solution of the Eikonal equation, which can be solved by solving a Hamiltonian system. This system is amenable of treatment from the poin…
Shapes of Auslander-Reiten Triangles
Edson Ribeiro Alvares, Sônia Maria Fernandes, Hernán Giraldo
Our main theorem classifies the Auslander-Reiten triangles according to properties of the morphisms involved. As a consequence, we are able to compute the mapping cone of an irredu…
