Two geometric models for graded skew-gentle algebras

Y Qiu, C Zhang, Y Zhou - arXiv preprint arXiv:2212.10369, 2022 - arxiv.org
In Part 1, we classify (indecomposable) objects in the perfect derived category $\mathrm
{per}\Lambda $ of a graded skew-gentle algebra $\Lambda $, generalizing …

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 …

Geometric model for module categories of Dynkin quivers via hearts of total stability conditions

W Chang, Y Qiu, X Zhang - Journal of Algebra, 2024 - Elsevier
We derive a geometric model for the module category mod k Q of a Dynkin quiver Q via the
heart of a total stability condition on the bounded derived category of mod k Q. As an …

On support τ-tilting graphs of gentle algebras

C Fu, S Geng, P Liu, Y Zhou - Journal of Algebra, 2023 - Elsevier
Let A be a finite-dimensional gentle algebra over an algebraically closed field. We
investigate the combinatorial properties of support τ-tilting graph of A. In particular, it is …

Geometric model for weighted projective lines of type

J Chen, S Ruan, H Zhang - arXiv preprint arXiv:2310.04695, 2023 - arxiv.org
We give a geometric model for the category of coherent sheaves over the weighted
projective line of type $(p, q) $ in terms of an annulus with marked points on its boundary …

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 …

Mutation graph of support -tilting modules over a skew-gentle algebra

P He, Y Zhou, B Zhu - arXiv preprint arXiv:2212.10880, 2022 - arxiv.org
Let $\mathcal {D} $ be a Hom-finite, Krull-Schmidt, 2-Calabi-Yau triangulated category with a
rigid object $ R $. Let $\Lambda=\operatorname {End} _ {\mathcal {D}} R $ be the …

Partially wrapped Fukaya categories of orbifold surfaces

S Barmeier, S Schroll, Z Wang - arXiv preprint arXiv:2407.16358, 2024 - arxiv.org
We give a complete description of partially wrapped Fukaya categories of graded orbifold
surfaces with stops. We show that a construction via global sections of a natural cosheaf of A …

A geometric model for the module category of a string algebra

K Baur, RC Simoes - arXiv preprint arXiv:2403.07810, 2024 - arxiv.org
In this paper, we give a geometric construction of string algebras and of their module
categories. Our approach uses dissections of punctured Riemann surfaces with extra data at …
