In this thesis we study the relation between scattering diagrams and deformations of holomorphic pairs, building on a recent work of Chan--Conan Leung--Ma. The new feature is the extended tropical vertex group where the scattering diagrams are defined. In addition, the extended tropical vertex provides interesting applications: on one hand we get a geometric interpretation of the wall-crossing formulas for coupled $2d$-$4d$ systems, previously introduced by Gaiotto--Moore--Neitzke. On the other…

INFINITESIMAL DEFORMATIONS AND THE EXTENDED TROPICAL VERTEX GROUP

I will discuss the relationship between scattering diagrams and infinitesimal deformations of holomorphic pairs, which Fukaya outlined in [4], and which I studied in my PhD thesis [3]. Scattering…

Scattering diagrams in mirror symmetry

Since the pioneering work of Kontsevich and Soibelman [33], scattering diagrams have started playing an important role in mirror symmetry, in particular the study of the reconstructing problem. This…

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 are…

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 constructed…

Open String Instantons and Relative Stable Morphisms

We show how topological open string theory amplitudes can be computed by using relative stable morphisms in the algebraic category. We achieve our goal by explicitly working through an example which…

The quantum tropical vertex

Gross-Pandharipande-Siebert have shown that the 2-dimensional Kontsevich-Soibelman scattering diagrams compute certain genus zero log Gromov-Witten invariants of log Calabi-Yau surfaces. We show that…

Deformations of holomorphic pairs and 2d-4d wall-crossing

We show how wall-crossing formulas in coupled 2d-4d systems, introduced by Gaiotto, Moore and Neitzke, can be interpreted geometrically in terms of the deformation theory of holomorphic pairs, given…

A differential-geometric approach to deformations of pairs (X, E)

Abstract This article gives an exposition of the deformation theory for pairs (X, E), where X is a compact complex manifold and E is a holomorphic vector bundle over X, adapting an analytic viewpoint…

SYZ mirror symmetry from Witten-Morse theory

This is a survey article on the recent progress in understanding the Strominger-Yau-Zaslow (SYZ) mirror symmetry conjecture, especially on the effect of quantum corrections, via Witten-Morse theory…

We explain our proof, joint with Mark Gross and Maxim Kontsevich, of conjectures of Fomin–Zelevinsky and Fock–Goncharov on canonical bases of cluster algebras. We interpret a cluster algebra as the…

Quantization of open-closed BCOV theory, I

This is the first in a series of papers which analyze the problem of quantizing the theory coupling Kodaira-Spencer gravity (or BCOV theory) on Calabi-Yau manifolds using the formalism for…
