Gentle algebras arising from surface triangulations

I Assem, T Brüstle, G Charbonneau-Jodoin… - Algebra & Number …, 2010 - msp.org
We associate an algebra A (Γ) to a triangulation Γ of a surface S with a set of boundary
marking points. This algebra A (Γ) is gentle and Gorenstein of dimension one. We also prove …

A geometric model for the module category of a gentle algebra

K Baur, R Coelho Simões - International Mathematics Research …, 2021 - academic.oup.com
In this article, gentle algebras are realised as tiling algebras, which are associated to partial
triangulations of unpunctured surfaces with marked points on the boundary. This notion of …

A complete derived invariant for gentle algebras via winding numbers and Arf invariants

C Amiot, PG Plamondon, S Schroll - Selecta Mathematica, 2023 - Springer
Gentle algebras are in bijection with admissible dissections of marked oriented surfaces. In
this paper, we further study the properties of admissible dissections and we show that silting …

Brauer graph algebras: a survey on Brauer graph algebras, associated gentle algebras and their connections to cluster theory

S Schroll - … methods, representation theory, and cluster algebras, 2018 - Springer
This survey starts with a motivation of the study of Brauer graph algebras by relating them to
special biserial algebras. The definition of Brauer graph algebras is given in great detail with …

[HTML][HTML] Trivial extensions of gentle algebras and Brauer graph algebras

S Schroll - Journal of Algebra, 2015 - Elsevier
We show that two well-studied classes of tame algebras coincide: namely, the class of
symmetric special biserial algebras coincides with the class of Brauer graph algebras. We …

[HTML][HTML] Combinatorial derived invariants for gentle algebras

D Avella-Alaminos, C Geiss - Journal of Pure and Applied Algebra, 2008 - Elsevier
We define derived equivalent invariants for gentle algebras, constructed in an easy
combinatorial way from the quiver with relations defining these algebras. Our invariants …

Singularity categories of gentle algebras

M Kalck - Bulletin of the London Mathematical Society, 2015 - Wiley Online Library
We determine the singularity category of an arbitrary finite‐dimensional gentle algebra Λ. It
is a finite product of n‐cluster categories of type A 1. Equivalently, it may be described as the …

A geometric realization of silting theory for gentle algebras

W Chang, S Schroll - Mathematische Zeitschrift, 2023 - Springer
A gentle algebra gives rise to a dissection of an oriented marked surface with boundary into
polygons and the bounded derived category of the gentle algebra has a geometric …

On auto-equivalences and complete derived invariants of gentle algebras

S Opper - arXiv preprint arXiv:1904.04859, 2019 - arxiv.org
We study triangulated categories which can be modeled by an oriented marked surface
$\mathcal {S} $ and a line field $\eta $ on $\mathcal {S} $. This includes bounded derived …

Discrete derived categories I: homomorphisms, autoequivalences and t-structures

N Broomhead, D Pauksztello, D Ploog - Mathematische Zeitschrift, 2017 - Springer
Discrete derived categories were studied initially by Vossieck (J Algebra 243: 168–176,
2001) and later by Bobiński et al.(Cent Eur J Math 2: 19–49, 2004). In this article, we …
