Semi-Invariant Rings: UFD and Codimension One Orbits

Charles Paquette, Deepanshu Prasad, David Wehlau

Let be a finite dimensional associative -algebra over an algebraically closed field of characteristic zero. To , we can associate its basic form tha…

Biserial algebras and generic bricks

Kaveh Mousavand, Charles Paquette

We consider generic bricks and use them in the study of arbitrary biserial algebras over algebraically closed fields. For a biserial algebra , we show that is brick-infinite…

Representations of free products of semisimple algebras via quivers

Andrew Buchanan, Ivan Dimitrov, Olivia Grace +3

Let denote an algebraically closed field and a free product of finitely many semisimple associative -algebras. We associate to a finite acyclic qui…

Minimal (-)tilting infinite algebras

Kaveh Mousavand, Charles Paquette

Motivated by a new conjecture on the behavior of bricks, we start a systematic study of minimal -tilting infinite algebras. In particular, we treat minimal -tilting infinite…

Subregular -rings of Coxeter systems via quiver path algebras

Ivan Dimitrov, Charles Paquette, David Wehlau +1

We study the subregular -ring of a Coxeter system , a subring of Lusztig's -ring. We prove that is isomorphic to a quotient of the path algebra of the doub…

Completions of discrete cluster categories of type

Charles Paquette, Emine Yildirim

We complete the discrete cluster categories of type as defined by Igusa and Todorov, by embedding such a discrete cluster category inside a larger one, and then taking…

Idempotent reduction for the finitistic dimension conjecture

Diego Bravo, Charles Paquette

In this note, we prove that if is an Artin algebra with a simple module of finite projective dimension, then the finiteness of the finitistic dimension of implies that…

Generators versus projective generators in abelian categories

Charles Paquette

Let be an essentially small abelian category. We prove that if admits a generator with right artinian, then $\mathcal{A…

Homological behavior of idempotent subalgebras and Ext algebras

Colin Ingalls, Charles Paquette

Let be a (left and right) Noetherian ring that is semiperfect. Let be an idempotent of and consider the ring and the semi-simple right -module $S_e…

Group actions on cluster algebras and cluster categories

Charles Paquette, Ralf Schiffler

We introduce admissible group actions on cluster algebras, cluster categories and quivers with potential and study the resulting orbit spaces. The orbit space of the cluster algebr…

Isotropic Schur roots

Charles Paquette, Jerzy Weyman

In this paper, we study the isotropic Schur roots of an acyclic quiver with vertices. We study the perpendicular category of a dimension vector and giv…

Cluster categories of type and triangulations of the infinite strip

Shiping Liu, Charles Paquette

We first study the (canonical) orbit category of the bounded derived category of finite dimensional representations of a quiver with no infinite path, and we pay more attention on…

Accumulation points of real Schur roots

Charles Paquette

Let be an algebraically closed field and be an acyclic quiver with vertices. Consider the category of finite dimensional representations of over .…

Homological dimensions for co-rank one idempotent subalgebras

Colin Ingalls, Charles Paquette

Let be an algebraically closed field and be a (left and right) Noetherian associative -algebra. Assume further that is either positively graded or semiperfect (this…

Semi-stable subcategories for Euclidean quivers

Colin Ingalls, Charles Paquette, Hugh Thomas

In this paper, we study the semi-stable subcategories of the category of representations of a Euclidean quiver, and the possible intersections of these subcategories. Contrary to t…

Standard components of a Krull-Schmidt category

Shiping Liu, Charles Paquette

We provide criteria for an Auslander-Reiten component having sections of a Krull-Schmidt category to be standard. Specializing to the category of finitely presented representations…

Almost split sequences and approximations

Shiping Liu, Puiman Ng, Charles Paquette

Let A be an exact category, that is, an extension-closed full subcategory of an abelian category. Firstly, we give some necessary and sufficient conditions for A to have almost spl…

A non-existence theorem for almost split sequences

Charles Paquette

Let k be a field, Q a quiver with countably many vertices and I an ideal of kQ such that kQ/I has finite dimensional Hom-spaces. In this note, we prove that there is no almost spli…

A proof of the strong no loop conjecture

Kiyoshi Igusa, Shiping Liu, Charles Paquette

The strong no loop conjecture states that a simple module of finite projective dimension over an artin algebra has no non-zero self-extension. The main result of this paper establi…
