We study the global dimension function $\operatorname{gldim}\colon\operatorname{Aut}\backslash\operatorname{Stab}\mathcal{D}/\mathbb{C}\to\mathbb{R}_{\ge0}$ on a quotient of the space of Bridgeland stability conditions on a triangulated category $\mathcal{D}$ as well as Toda's Gepner equation $\Phi(\sigma)=s\cdot\sigma$ for some $\sigma\in\operatorname{Stab}\mathcal{D}$ and $(\Phi,s)\in\operatorname{Aut}\mathcal{D}\times\mathbb{C}$. We prove the uniqueness (up to the $\mathbb{C}$-action) of the… Expand

Contractible flow of stability conditions via global dimension function
We introduce an analytic method that uses the global dimension function $\operatorname{gldim}$ to produce contractible flows on the space $\operatorname{Stab}\mathcal{D}$ of stability conditions on aExpand
Serre dimension and stability conditions
We study relations between the Serre dimension defined as the growth of entropy of the Serre functor and the global dimension of Bridgeland stability conditions due to Ikeda-Qiu. A fundamentalExpand
Cambrian combinatorics on quiver representations (type A)
This paper presents a new geometric model of the Auslander-Reiten quiver of a type A quiver. We introduce a new Catalan object which we call a maximal almost rigid representation. We show that itsExpand


Contractible stability spaces and faithful braid group actions
We prove that any `finite-type' component of a stability space of a triangulated category is contractible. The motivating example of such a component is the stability space of the Calabi--Yau-$N$Expand
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'sExpand
Abstract We study the fundamental groups of the exchange graphs for the bounded derived category D ( Q ) of a Dynkin quiver Q and the finite-dimensional derived category D ( Γ N Q ) of theExpand
Gepner type stability conditions on graded matrix factorizations
We introduce the notion of Gepner type Bridgeland stability conditions on triangulated categories, which depends on a choice of an autoequivalence and a complex number. We conjecture the existence ofExpand
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 ofExpand
Stability conditions on CYN categories associated to An-quivers and period maps
In this paper, we study the space of stability conditions on a certain N- Calabi-Yau (CYN) category associated to an An-quiver. Recently, Bridgeland and Smith constructed stability conditions on someExpand
Braid group actions on derived categories of coherent sheaves
This paper gives a construction of braid group actions on the derived category of coherent sheaves on a variety $X$. The motivation for this is Kontsevich's homological mirror conjecture, togetherExpand
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 acyclicExpand
Gepner Type Stability Condition via Orlov/Kuznetsov Equivalence
We show the existence of Gepner type Bridgeland stability conditions on the triangulated categories of graded matrix factorizations associated with homogeneous polynomials which define general cubicExpand
Stability conditions and Kleinian singularities
We describe (connected components of) the spaces of stability conditions on certain triangulated categories associated to Dynkin diagrams. These categories can be defined either algebraically viaExpand
