Starting with a gentle approach to the Alday–Gaiotto–Tachikawa (AGT) correspondence
from its 6d origin, these notes provide a wide (albeit shallow) survey of the literature on …

We study the spectrum of BPS particles on the Coulomb branch of five-dimensional
superconformal field theories (5d SCFTs) compactified on a circle. By engineering these …

A bstract We study various non-perturbative approaches to the quantization of the Seiberg-
Witten curve of\(\mathcal {N}\)= 2, SU (2) super Yang-Mills theory, which is closely related to …

A bstract We study the Gauge/Bethe correspondence for two-dimensional\(\mathcal {N}\)=(2,
2) supersymmetric quiver gauge theories associated with toric Calabi-Yau three-folds …

The stable envelopes of Okounkov et al. realize some representations of quantum algebras
associated to quivers, using geometry. We relate these geometric considerations to quantum …

Quantum periods appear in many contexts, from quantum mechanics to local mirror
symmetry. They can be described in terms of topological string free energies and Wilson …

We study the non-perturbative quantum geometry of the open and closed topological string
on the resolved conifold and its mirror. Our tools are finite difference equations in the open …

A bstract We study in detail the Schrödinger equation corresponding to the four dimensional
SU (2)\(\mathcal {N}\)= 2 SQCD theory with one flavour. We calculate the Voros symbols, or …

We propose a connection between 3d-5d exponential networks and exact WKB for
difference equations associated to five dimensional Seiberg-Witten curves, or equivalently …

Topological string theory near the conifold point of a Calabi-Yau threefold gives rise to
factorially divergent power series which encode the all-genus enumerative information …
