On universal deformation rings and stable homogeneous tubes

Jhony F. Caranguay-Mainguez, Pedro Rizzo, Jose A. Velez-Marulanda

Let $k$ be a field of any characteristic and let $Λ$ be a finite dimensional $k$ -algebra. We prove that if $V$ is a finite dimensional right $Λ$ -module that lies…

Universal deformation rings of a special class of modules over generalized Brauer tree algebras

Jhony F. Caranguay-Mainguez, Pedro Rizzo, José A. Vélez-Marulanda

Let $k$ be an algebraically closed field and $Λ$ a generalized Brauer tree algebra over $k$ . We compute the universal deformation rings of the periodic string modules over…

On universal deformation rings of modules over a certain class of symmetric algebras of finite representation type

Jhony F. Caranguay-Mainguez, Pedro Rizzo, Jose A. Velez-Marulanda

Let $k$ be an algebraically closed field. Recently, K. Erdmann classified the symmetric $k$ -algebras $Λ$ of finite representation type such that every non-project…

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…

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…
