Working over various graded Lie algebras and in arbitrary dimension, we express scattering diagrams and theta functions in terms of counts of tropical curves/disks, weighted by multiplicities given in terms of iterated Lie brackets. Over the tropical vertex group, our tropical curve counts are known to give certain descendant log Gromov-Witten invariants. Working over the quantum torus algebra yields theta functions for quantum cluster varieties, and our tropical description sets up for… Expand
Donaldson–Thomas invariants from tropical disks
We prove that the quantum DT invariants associated to quivers with genteel potential can be expressed in terms of certain refined counts of tropical disks. This is based on a quantum version ofExpand
Refined Scattering Diagrams and Theta Functions From Asymptotic Analysis of Maurer–Cartan Equations
We further develop the asymptotic analytic approach to the study of scattering diagrams. We do so by analyzing the asymptotic behavior of Maurer–Cartan elements of a (dg) Lie algebra constructedExpand
The Higher Dimensional Tropical Vertex
We study log Calabi-Yau varieties obtained as a blow-up of a toric variety along hypersurfaces in its toric boundary. Mirrors to such varieties are constructed by Gross-Siebert from a canonicalExpand
Refined count of real oriented rational curves
We introduce a quantum index for oriented real curves inside toric varieties. This quantum index is related to the computation of the area of the amoeba of the curve for some chosen 2-form. We thenExpand
I will begin with a brief introduction to log geometry and log Gromov-Witten theory, and I will explain tropicalization from this log perspective. I will then give an overview of cluster varieties,Expand
Quantum mirrors of log Calabi–Yau surfaces and higher-genus curve counting
Gross, Hacking and Keel have constructed mirrors of log Calabi–Yau surfaces in terms of counts of rational curves. Using $q$-deformed scattering diagrams defined in terms of higher-genus logExpand
Theta bases are atomic
Fock and Goncharov conjectured that the indecomposable universally positive (i.e. atomic) elements of a cluster algebra should form a basis for the algebra. This was shown to be false by Lee, Li andExpand
Strong positivity for the skein algebras of the $4$-punctured sphere and of the $1$-punctured torus
The Kauffman bracket skein algebra is a quantization of the algebra of regular functions on the $SL_2$ character variety of a topological surface. We realize the skein algebra of the $4$-puncturedExpand
Scattering diagrams, stability conditions, and coherent sheaves on $\mathbb{P}^2$
We show that a purely algebraic structure, a two-dimensional scattering diagram, describes a large part of the wall-crossing behavior of moduli spaces of Bridgeland semistable objects in the derivedExpand
Stable maps to Looijenga pairs: orbifold examples
In [15] we established a series of correspondences relating five enumerative theories of log Calabi–Yau surfaces, i.e. pairs (Y,D) with Y a smooth projective complex surface and D = D1 + · · ·+Dl anExpand


Canonical bases for cluster algebras
In [GHK11], Conjecture 0.6, the first three authors conjectured that the ring of regular functions on a natural class of affine log Calabi-Yau varieties (those with maximal boundary) has a canonicalExpand
Quivers, curves, and the tropical vertex
Elements of the tropical vertex group are formal families of symplectomorphisms of the 2-dimensional algebraic torus. Commutators in the group are related to Euler characteristics of the moduliExpand
The tropical vertex
Elements of the tropical vertex group are formal families of symplectomorphisms of the 2-dimensional algebraic torus. We prove ordered product factorizations in the tropical vertex group areExpand
Refined curve counting on complex surfaces
We define refined invariants which "count" nodal curves in sufficiently ample linear systems on surfaces, conjecture that their generating function is multiplicative, and conjecture explicit formulasExpand
Tropical refined curve counting via motivic integration
We propose a geometric interpretation of Block and G\"ottsche's refined tropical curve counting invariants in terms of virtual $\chi_{-y}$-specializations of motivic measures of semialgebraic sets inExpand
Intersection Theory on Tropicalizations of Toroidal Embeddings
We show how to equip the cone complexes of toroidal embeddings with additional structure that allows to define a balancing condition for weighted subcomplexes. We then proceed to develop theExpand
Scattering diagrams, Hall algebras and stability conditions
To any quiver with relations we associate a consistent scattering diagram taking values in the motivic Hall algebra of its category of representations. We show that the chamber structure of thisExpand
Quantum indices and refined enumeration of real plane curves
We associate a half-integer number, called {\em the quantum index}, to algebraic curves in the real plane satisfying to certain conditions. The area encompassed by the logarithmic image of suchExpand
Mirror symmetry for P^2 and tropical geometry
This paper explores the relationship between mirror symmetry for P^2, at the level of big quantum cohomology, and tropical geometry. The mirror of P^2 is typically taken to be ((C^*)^2,W), where W isExpand
Enumerative tropical algebraic geometry in R^2
The paper establishes a formula for enumeration of curves of arbitrary genus in toric surfaces. It turns out that such curves can be counted by means of certain lattice paths in the Newton polygon.Expand
