On the Irreducible Morphisms for Skew group algebras
Shantanu Sardar, Alfredo Gonzalez Chaio, Sonia Trepode
For an algebraically closed field K, let G be a finite abelian group of K-linear automorphisms of a finite-dimensional path algebra KQ of a quiver Q. Under certain assumptions on t…
On the global dimension three endomorphism algebras of the minimal generator-cogenerator
Edson Ribeiro Alvares, Clezio Aparecido Braga, Sonia Trepode +1
The main goal of this paper is to study the class of algebras for which the global dimension of the endomorphism ring of the generator-cogenerator, given by the sum of the projecti…
Endomorphism algebras of silting complexes
Lidia Angeleri Hügel, Marcelo Lanzilotta, Jifen Liu +1
We consider endomorphism algebras of -term silting complexes in derived categories of hereditary algebras, and we show that the module category of such an endomorphism algebra h…
Characterisations of trivial extensions
Elsa Fernandez, Sibylle Schroll, Hipolito Treffinger +2
In this paper we give a characterisation of trivial extension algebras in terms of quivers with relations. This result is based on a explicit description of the ideal of relations…
From the potential to the first Hochschild cohomology group of a cluster tilted algebra
Ibrahim Assem, Juan Carlos Bustamante, Sonia Trepode +1
The objective of this paper is to give a concrete interpretation of the dimension of the first Hochschild cohomology space of a cyclically oriented or tame cluster tilted algebra i…
The fundamental group of an algebra with strongly simply connected Galois covering
Claudia Chaio, Diane Castonguay, Sonia Trepode
In this work, we prove that if a triangular algebra admits a strongly simply connected universal Galois covering for a given presentation then the fundamental group associated…
