Skew-group -categories as Fukaya categories of orbifolds

C Amiot, PG Plamondon - arXiv preprint arXiv:2405.15466, 2024 - arxiv.org
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 …

Relative Fukaya Categories via Gentle Algebras

J van de Kreeke - arXiv preprint arXiv:2305.09112, 2023 - arxiv.org
Relative Fukaya categories are hard to construct. In this paper, we provide a very explicit
construction in the case of punctured surfaces. The starting point is the gentle algebra …

Cluster categories for marked surfaces: punctured case

Y Qiu, Y Zhou - Compositio Mathematica, 2017 - cambridge.org
We study cluster categories arising from marked surfaces (with punctures and non-empty
boundaries). By constructing skewed-gentle algebras, we show that there is a bijection …

Recollements of partially wrapped Fukaya categories and surface cuts

W Chang, H Jin, S Schroll - arXiv preprint arXiv:2206.11196, 2022 - arxiv.org
In this paper we use recollements to investigate partially wrapped Fukaya categories of
surfaces with marked points. In particular, we show that cutting surfaces gives rise to …

[PDF][PDF] Graded decorated marked surfaces: Calabi-Yau-X categories of gentle algebras

A Ikeda, Y Qiu, Y Zhou - arXiv preprint arXiv:2006.00009, 2020 - researchgate.net
Let S a graded marked surface. We construct a string model for Calabi-Yau-X category DX
(S△), via graded decorated marked surfaces S△. We prove the isomorphism between the …

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 …

Recollements for graded gentle algebras from spherical band objects

P Bodin - arXiv preprint arXiv:2407.04374, 2024 - arxiv.org
In this paper we study the localization of a derived category of a graded gentle algebra by a
subcategory generated by a spherical band object. This object corresponds to a simple …

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 …

Indecomposable objects in the derived category of a skew-gentle algebra using orbifolds

C Amiot - arXiv preprint arXiv:2107.02646, 2021 - arxiv.org
Skew-gentle algebras are skew-group algebras of certain gentle algebras endowed with a Z
2-action. Using the topological description of Opper, Plamondon and Schroll in [OPS] for the …

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 …
