Decorated Marked Surfaces III: The Derived Category of a Decorated Marked Surface

  title={Decorated Marked Surfaces III: The Derived Category of a Decorated Marked Surface},
  author={Aslak Bakke Buan and Yu Qiu and Yu Zhou},
  journal={International Mathematics Research Notices},
We study the Ginzburg dg algebra $\Gamma _{\mathbf {T}}$ associated with the quiver with potential arising from a triangulation $\mathbf {T}$ of a decorated marked surface ${\mathbf {S}}_\bigtriangleup$, in the sense of [22]. We show that there is a canonical way to identify all finite-dimensional derived categories $\operatorname {\mathcal {D}}_{fd}(\Gamma _{\mathbf {T}})$, denoted by $\operatorname {\mathcal {D}}_{fd}({\mathbf {S}}_\bigtriangleup )$. As an application, we show that the…

Decorated Marked Surfaces: Calabi-Yau categories and related topics
This is a survey on the project `Decorated Marked Surfaces', where we introduce the decoration $\Delta$ on a marked surfaces $\mathbf{S}$, to study Calabi-Yau-2 (cluster) categories, Calabi-Yau-3
Cluster exchange groupoids and framed quadratic differentials
We introduce the cluster exchange groupoid associated to a non-degenerate quiver with potential, as an enhancement of the cluster exchange graph. In the case that arises from an (unpunctured) marked
Topological structure of spaces of stability conditions and topological Fukaya type categories
This is a survey on two closely related subjects. First, we review the study of topological structure of `finite type' components of spaces of Bridgeland's stability conditions on triangulated

We survey various generalizations of braid groups for quivers with superpotential and focus on the cluster braid groups, which are introduced in a joint work with King (2018). Our motivations come


Decorated marked surfaces (part B): topological realizations
We study categories associated to a decorated marked surface $${\mathbf {S}}_\bigtriangleup $$S△, which is obtained from an unpunctured marked surface $$\mathbf {S}$$S by adding a set of decorating
Decorated marked surfaces: spherical twists versus braid twists
We are interested in the 3-Calabi-Yau categories $${\mathcal {D}}$$D arising from quivers with potential associated to a triangulated marked surface $$\mathbf {S}$$S (without punctures). We prove

We study the 3-Calabi-Yau categories $\mathcal{D}$ arising from quivers with potential associated to a decorated marked surface $\mathbf{S}_\bigtriangleup$ introduced by the first author. We prove
Stability conditions on triangulated categories
This paper introduces the notion of a stability condition on a triangulated category. The motivation comes from the study of Dirichlet branes in string theory, and especially from M.R. Douglas's
Deformed Calabi–Yau completions
Abstract We define and investigate deformed n-Calabi–Yau completions of homologically smooth differential graded (= dg) categories. Important examples are: deformed preprojective algebras of
Weight structures and simple dg modules for positive dg algebras
Using techniques due to Dwyer-Greenlees-Iyengar we construct weight structures in triangulated categories generated by compact objects. We apply our result to show that, for a dg category whose
Exchange graphs and Ext quivers
Abstract We study the oriented exchange graph EG ∘ ( Γ N Q ) of reachable hearts in the finite-dimensional derived category D ( Γ N Q ) of the CY-N Ginzburg algebra Γ N Q associated to an acyclic
Deriving DG categories
— We investigate the (unbounded) derived category of a differential Z-graded category (=DG category). As a first application, we deduce a "triangulated analogue" (4.3) of a theorem of Freyd's [5],
Quivers with potentials associated to triangulated surfaces
We attempt to relate two recent developments: cluster algebras associated to triangulations of surfaces by Fomin-Shapiro-Thurston, and quivers with potentials and their mutations introduced by
Calabi-Yau algebras
We introduce some new algebraic structures arising naturally in the geometry of Calabi-Yau manifolds and mirror symmetry. We give a universal construction of Calabi-Yau algebras in terms of a
