Derived categories of skew-gentle algebras and orbifolds

D Labardini-Fragoso, S Schroll… - Glasgow Mathematical …, 2022 - cambridge.org
Skew-gentle algebras are a generalisation of the well-known class of gentle algebras with
which they share many common properties. In this work, using non-commutative Gröbner …

Gorenstein properties of simple gluing algebras

M Lu - Algebras and Representation Theory, 2019 - Springer
For given bound quiver algebras A and B, we obtain a new algebra Λ, called the simple
gluing algebra, by identifying two vertices. We investigate the Gorenstein homological …

Derived tame Nakayama algebras

V Bekkert, H Giraldo, J Vélez-Marulanda - Proceedings of the American …, 2021 - ams.org
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 …

Moduli of Representations of Skewed-Gentle Algebras

C Gilbert - arXiv preprint arXiv:2208.00336, 2022 - arxiv.org
We prove irreducible components of moduli spaces of semistable representations of skewed-
gentle algebras, and more generally, clannish algebras, are isomorphic to products of …

Singular equivalences induced by ring extensions

Y Qin - arXiv preprint arXiv:2403.12412, 2024 - arxiv.org
Let $ B\subseteq A $ be an extension of finite dimensional algebras. We provide a sufficient
condition for the existence of triangle equivalences of singularity categories (resp …

The stable category of Gorenstein-projective modules over a monomial algebra

T Honma, S Usui - arXiv preprint arXiv:2407.04912, 2024 - arxiv.org
Let $\Lambda $ be an arbitrary monomial algebra. We investigate the stable category
$\underline {\operatorname {Gproj}}^{\mathbb {Z}}\Lambda $ of graded Gorenstein …

Cohen–Macaulay Auslander algebras of skewed-gentle algebras

X Chen, M Lu - Communications in Algebra, 2017 - Taylor & Francis
For any skewed-gentle algebra, we characterize its indecomposable Gorenstein projective
modules explicitly and describe its Cohen–Macaulay Auslander algebra. We prove that …

Desingularization of quiver Grassmannians for gentle algebras

X Chen, M Lu - Algebras and Representation Theory, 2016 - Springer
Abstract In (Cerulli Irelli et al., Adv. Math. 245 (1) 182–207 2013), Cerulli Irelli-Feigin-
Reineke construct a desingularization of quiver Grassmannians for Dynkin quivers …

[HTML][HTML] Universal deformation rings of finitely generated Gorenstein-projective modules over finite dimensional algebras

V Bekkert, H Giraldo, JA Vélez-Marulanda - Journal of Pure and Applied …, 2020 - Elsevier
Let k be a field of arbitrary characteristic, let Λ be a finite dimensional k-algebra, and let V be
a finitely generated Λ-module. FM Bleher and the third author previously proved that V has a …

A Geometric Model for Syzygies Over 2-Calabi–Yau Tilted Algebras II

R Schiffler, K Serhiyenko - International Mathematics Research …, 2024 - academic.oup.com
In this article, we continue the study of a certain family of 2-Calabi–Yau tilted algebras,
called dimer tree algebras. The terminology comes from the fact that these algebras can also …
