Resurgent asymptotics of Jackiw–Teitelboim gravity and the nonperturbative topological recursion

B Eynard, E Garcia-Failde, P Gregori, D Lewański… - Annales Henri …, 2024 - Springer
Jackiw–Teitelboim dilaton quantum gravity localizes on a double-scaled random-matrix
model, whose perturbative free energy is an asymptotic series. Understanding the resurgent …

Double Hurwitz numbers: polynomiality, topological recursion and intersection theory

G Borot, N Do, M Karev, D Lewański… - Mathematische …, 2023 - Springer
Double Hurwitz numbers enumerate branched covers of CP 1 with prescribed ramification
over two points and simple ramification elsewhere. In contrast to the single case, their …

Whittaker vectors for -algebras from topological recursion

G Borot, V Bouchard, NK Chidambaram, T Creutzig - Selecta Mathematica, 2024 - Springer
We identify Whittaker vectors for W k (g)-modules with partition functions of higher Airy
structures. This implies that Gaiotto vectors, describing the fundamental class in the …

Elements of spin Hurwitz theory: closed algebraic formulas, blobbed topological recursion, and a proof of the Giacchetto–Kramer–Lewański conjecture

A Alexandrov, S Shadrin - Selecta Mathematica, 2023 - Springer
In this paper, we discuss the properties of the generating functions of spin Hurwitz numbers.
In particular, for spin Hurwitz numbers with arbitrary ramification profiles, we construct the …

On the Goulden–Jackson–Vakil conjecture for double Hurwitz numbers

N Do, D Lewański - Advances in Mathematics, 2022 - Elsevier
Abstract Goulden, Jackson and Vakil observed a polynomial structure underlying one-part
double Hurwitz numbers, which enumerate branched covers of CP 1 with prescribed …

KP hierarchy for Hurwitz-type cohomological field theories

R Kramer - arXiv preprint arXiv:2107.05510, 2021 - arxiv.org
We generalise a result of Kazarian regarding Kadomtsev-Petviashvili integrability for single
Hodge integrals to general cohomological field theories related to Hurwitz-type counting …

Kac-Schwarz operators of type B, quantum spectral curves, and spin Hurwitz numbers

C Ji, Z Wang, C Yang - Journal of Geometry and Physics, 2023 - Elsevier
Given a tau-function τ (t) of the BKP hierarchy satisfying τ (0)= 1, we discuss the relation
between its BKP-affine coordinates on the isotropic Sato Grassmannian and its BKP-wave …

BKP-Affine Coordinates and Emergent Geometry of Generalized Br\'ezin-Gross-Witten Tau-Functions

Z Wang, C Yang, Q Zhang - arXiv preprint arXiv:2301.01131, 2023 - arxiv.org
Following Zhou's framework, we consider the emergent geometry of the generalized Br\'ezin-
Gross-Witten models whose partition functions are known to be a family of tau-functions of …

Connected (n, m)-point functions of diagonal 2-BKP tau-functions and spin double Hurwitz numbers

Z Wang, C Yang - Journal of Mathematical Physics, 2023 - pubs.aip.org
We derive an explicit formula for connected (n, m)-point functions associated with an
arbitrary diagonal tau-function of the 2-BKP hierarchy using the computation of neutral …

The spin Gromov-Witten/Hurwitz correspondence for P1

A Giacchetto, R Kramer, D Lewanski… - arXiv preprint arXiv …, 2022 - ems.press
We study the spin Gromov–Witten theory of P1. Using the standard torus action on P1, we
prove that the associated equivariant potential can be expressed by means of operator …
