A geometric model for the derived category of gentle algebras

S Opper, PG Plamondon, S Schroll - arXiv preprint arXiv:1801.09659, 2018 - arxiv.org
In this paper, we construct a geometric model for the bounded derived category of a gentle
algebra. The construction is based on the ribbon graph associated to a gentle algebra by the …

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 …

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 the derived categories of gentle and skew-gentle algebras: homological algebra and matrix problems

I Burban, Y Drozd - arXiv preprint arXiv:1706.08358, 2017 - arxiv.org
In this paper, we investigate properties of the bounded derived category of finite dimensional
modules over a gentle or skew-gentle algebra. We show that the Rouquier dimension of the …

Torsion pairs and cosilting in type A˜

K Baur, R Laking - Journal of Pure and Applied Algebra, 2022 - Elsevier
Torsion pairs in the category of finitely presented modules over a noetherian ring can be
parametrised by the class of cosilting modules. In this paper, we characterise such modules …

[HTML][HTML] The Ziegler spectrum for derived-discrete algebras

KK Arnesen, R Laking, D Pauksztello, M Prest - Advances in Mathematics, 2017 - Elsevier
Let Λ be a derived-discrete algebra. We show that the Krull–Gabriel dimension of the
homotopy category of projective Λ-modules, and therefore the Cantor–Bendixson rank of its …

Skew-group A∞-categories as Fukaya categories of orbifolds

C Amiot, PG Plamondon - 2024 - cnrs.hal.science
We study the partially wrapped Fukaya category of a surface with boundary with an action of
a group of order two. Inspired by skew-group algebras and categories, we define the notion …

Oriented flip graphs, noncrossing tree partitions, and representation theory of tiling algebras

A Garver, T McConville - Glasgow Mathematical Journal, 2020 - cambridge.org
The purpose of this paper is to understand lattices of certain subcategories in module
categories of representation-finite gentle algebras called tiling algebras, as introduced by …
