On the Number of Exceptional Pairs Over a Class of Nakayama Algebras

Pedro Fernando Fernández Espinosa, David Reynoso-Mercado

In this paper some combinatorial and homological tools are used to describe and give an explicit formula for the number of exceptional pairs (exceptional sequences of length two) f…

Standard automorphisms of semisimple Lie algebras and their relations

David Reynoso-Mercado

Let be the simple Lie algebra of square matrices with zero trace. There are certain relations concerning standard automorphisms that are consider…

About UMP algebras and a special classification case

Jhony F. Caranguay-Mainguez, Andrés Franco, David Reynoso-Mercado +1

The class of UMP algebras arises in several classification problems in the context of derived categories of finite-dimensional algebras. In this paper we define the class of UMP al…

UMP Monomial Algebras: Combinatorial and Homological Consequences

Jhony Caranguay-Mainguez, Andrés Franco, David Reynoso-Mercado +1

In this paper, we apply the techniques developed in [5] to present several consequences of studying UMP algebras and the ramifications graph of a monomial bound quiver algebra. Spe…

A model for the canonical algebras of bimodules type (1, 4) over truncated polynomial rings

Christof Geiß, David Reynoso-Mercado

Let be the field of complex Laurent series. We use Galois descent techniques to show that the simple regular representations of the species of type $(1,\,…
