Ramifications of Hurwitz theory, KP integrability and quantum curves

A Alexandrov, D Lewanski, S Shadrin - Journal of High Energy Physics, 2016 - Springer
A bstract In this paper we revisit several recent results on monotone and strictly monotone

Integrals of ψ-classes over double ramification cycles

A Buryak, S Shadrin, L Spitz… - American Journal of …, 2015 - muse.jhu.edu
A double ramification cycle, or DR-cycle, is a codimension $ g $ cycle in the moduli space
$\overline {\mathcal M} _ {g, n} $ of stable curves. Roughly speaking, given a list of integers …

A new spin on Hurwitz theory and ELSV via theta characteristics

A Giacchetto, R Kramer, D Lewański - arXiv preprint arXiv:2104.05697, 2021 - arxiv.org
We study spin Hurwitz numbers, which count ramified covers of the Riemann sphere with a
sign coming from a theta characteristic. These numbers are known to be related to Gromov …

The spectral curve and the Schrödinger equation of double Hurwitz numbers and higher spin structures

M Mulase, S Shadrin, L Spitz - arXiv preprint arXiv:1301.5580, 2013 - arxiv.org
We derive the spectral curves for $ q $-part double Hurwitz numbers, $ r $-spin simple
Hurwitz numbers, and arbitrary combinations of these cases, from the analysis of the …

Orbifold Hurwitz numbers and Eynard-Orantin invariants

N Do, O Leigh, P Norbury - arXiv preprint arXiv:1212.6850, 2012 - arxiv.org
We prove that a generalisation of simple Hurwitz numbers due to Johnson, Pandharipande
and Tseng satisfy the topological recursion of Eynard and Orantin. This generalises the …

Explicit closed algebraic formulas for Orlov–Scherbin -point functions

B Bychkov, P Dunin-Barkowski, M Kazarian… - Journal de l'École …, 2022 - numdam.org
We derive a new explicit formula in terms of sums over graphs for the n-point correlation
functions of general formal weighted double Hurwitz numbers coming from the Kadomtsev …

The power sums involving Fibonacci polynomials and their applications

L Chen, X Wang - Symmetry, 2019 - mdpi.com
The Girard and Waring formula and mathematical induction are used to study a problem
involving the sums of powers of Fibonacci polynomials in this paper, and we give it …

Towards studying the structure of triple Hurwitz numbers

RXF Chen - arXiv preprint arXiv:2308.08455, 2023 - arxiv.org
Going beyond the studies of single and double Hurwitz numbers, we report some progress
towards studying Hurwitz numbers which correspond to ramified coverings of the Riemann …
