We give a geometric realization, the tagged rotation, of the AR-translation on the generalized cluster category associated to a surface $$\mathbf {S}$$S with marked points and non-empty boundary, which generalizes Brüstle–Zhang’s result for the puncture free case. As an application, we show that the intersection of the shifts in the 3-Calabi–Yau derived category $$\mathrm{\mathcal {D} }(\Gamma _{\mathbf {S}})$$D(ΓS) associated to the surface and the corresponding Seidel–Thomas braid group of… 
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
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
Density of g-Vector Cones From Triangulated Surfaces
We study $g$-vector cones associated with clusters of cluster algebras defined from a marked surface $(S,M)$ of rank $n$. We determine the closure of the union of $g$-vector cones associated with all
On a family of Caldero–Chapoton algebras that have the Laurent phenomenon
We realize a family of generalized cluster algebras as Caldero-Chapoton algebras of quivers with relations. Each member of this family arises from an unpunctured polygon with one orbifold point of
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 between tagged curves and
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 third author.
Derived invariants for surface cut algebras II: the punctured case
For each algebra of global dimension 2 arising from the quiver with potential associated to a triangulation of an unpunctured surface, Amiot-Grimeland have defined an integer-valued function on the
Non-leaving-face property for marked surfaces
We consider the polytope arising from a marked surface by flips of triangulations. D. D. Sleator, R. E. Tarjan, and W. P. Thurston [J. Amer. Math. Soc., 1988, 1(3): 647–681] studied the diameter of
Minimal length maximal green sequences and triangulations of polygons
We use combinatorics of quivers and the corresponding surfaces to study maximal green sequences of minimal length for quivers of type $$\mathbb {A}$$A. We prove that such sequences have length
Oriented flip graphs of polygonal subdivisions and noncrossing tree partitions
It is proved that the oriented flip graph is a polygonal, congruence-uniform lattice, which generalizes the classical lattice of noncrossing set partitions and inherits a cyclic action from its congruent lattice structure.


C-sortable words as green mutation sequences
Let $Q$ be an acyclic quiver and $\mathbf{s}$ be a sequence with elements in the vertex set $Q_0$. We describe an induced sequence of simple (backward) tilting in the bounded derived category
A Primer on Mapping Class Groups (Pms-49)
The study of the mapping class group Mod(S) is a classical topic that is experiencing a renaissance. It lies at the juncture of geometry, topology, and group theory. This book explains as many
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 between tagged curves and
Cluster-tilted algebras are Gorenstein and stably Calabi–Yau
Abstract We prove that in a 2-Calabi–Yau triangulated category, each cluster tilting subcategory is Gorenstein with all its finitely generated projectives of injective dimension at most one. We show
On the cluster category of a marked surface without punctures
We study in this paper the cluster category C(S,M) of a marked surface (S,M). We explicitly describe the objects in C(S,M) as direct sums of homotopy classes of curves in (S,M) and one-parameter
We study (the principal component of) the oriented exchange graph of hearts in the finite-dimensional derived category D( N Q) of the Calabi-Yau-N Ginzburg algebra associated to an acyclic quiver Q.
Quivers with potentials associated to triangulated surfaces, Part III: tagged triangulations and cluster monomials
Abstract To each tagged triangulation of a surface with marked points and non-empty boundary we associate a quiver with potential in such a way that whenever we apply a flip to a tagged triangulation
Moduli spaces of local systems and higher Teichmüller theory
Let G be a split semisimple algebraic group over Q with trivial center. Let S be a compact oriented surface, with or without boundary. We define positive representations of the fundamental group of S
Quivers with potentials associated to triangulated surfaces, part IV: removing boundary assumptions
We prove that the quivers with potentials associated with triangulations of surfaces with marked points, and possibly empty boundary, are non-degenerate, provided the underlying surface with marked
Cluster algebras via cluster categories with infinite-dimensional morphism spaces
Abstract We apply our previous work on cluster characters for Hom-infinite cluster categories to the theory of cluster algebras. We give a new proof of Conjectures 5.4, 6.13, 7.2, 7.10 and 7.12 of
