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
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
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 …

A geometric model for the derived category of gentle algebras
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
