The Witten-Kontsevich theorem states that a certain generating function for intersection numbers on the moduli space of stable curves is a tau-function for the KdV integrable hierarchy. This generating function can be recovered via the topological recursion applied to the Airy curve $x=\frac{1}{2}y^2$. In this paper, we consider the topological recursion applied to the irregular spectral curve $xy^2=\frac{1}{2}$, which we call the Bessel curve. We prove that the associated partition function is… 
Topological recursion and uncoupled BPS structures II: Voros symbols and the $\tau$-function
We continue our study of the correspondence between BPS structures and topological recursion in the uncoupled case, this time from the viewpoint of quantum curves. For spectral curves of

In this paper, we continue our investigation of the triple Hodge integrals satisfying the Calabi–Yau condition. For the tau-functions, which generate these integrals, we derive the complete families

A bstractWe investigate supereigenvalue models in the Ramond sector and their recursive structure. We prove that the free energy truncates at quadratic order in Grassmann coupling constants, and
Higher Br\'ezin-Gross-Witten tau-functions and intersection theory of Witten's and Norbury's classes
. In this paper, we consider the higher Br´ezin–Gross–Witten tau-functions, given by the matrix integrals. For these tau-functions we construct the canonical Kac–Schwarz operators, quantum spectral
Cut-and-join operators in cohomological field theory and topological recursion
We construct a cubic cut-and-join operator description for the partition function of the Chekhov–Eynard–Orantin topological recursion for a local spectral curve with simple ramification points. In
On tau-functions for the KdV hierarchy
For an arbitrary solution to the KdV hierarchy, the generating series of logarithmic derivatives of the tau-function of the solution can be expressed by the basic matrix resolvent via algebraic
Higher Airy structures, W algebras and topological recursion
We define higher quantum Airy structures as generalizations of the Kontsevich-Soibelman quantum Airy structures by allowing differential operators of arbitrary order (instead of only quadratic). We
Enumerative geometry via the moduli space of super Riemann surfaces
In this paper we relate volumes of moduli spaces of super Riemann surfaces to integrals over the moduli space of stable Riemann surfaces $\overline{\cal M}_{g,n}$. This allows us to use a recursion
Topological recursion with hard edges
We prove a Givental type decomposition for partition functions that arise out of topological recursion applied to spectral curves. Copies of the Konstevich–Witten KdV tau function arise out of
Integrable Differential Systems of Topological Type and Reconstruction by the Topological Recursion
Starting from a $$d\times d$$d×d rational Lax pair system of the form $$\hbar \partial _x \Psi = L\Psi $$ħ∂xΨ=LΨ and $$\hbar \partial _t \Psi =R\Psi $$ħ∂tΨ=RΨ, we prove that, under certain


The spectral curve of the Eynard-Orantin recursion via the Laplace transform
The Eynard-Orantin recursion formula provides an effective tool for certain enumeration problems in geometry. The formula requires a spectral curve and the recursion kernel. We present a uniform
Quantum curves for the enumeration of ribbon graphs and hypermaps
The topological recursion of Eynard and Orantin governs a variety of problems in enumerative geometry and mathematical physics. The recursion uses the data of a spectral curve to define an infinite
Virasoro Constraints and Topological Recursion for Grothendieck’s Dessin Counting
We compute the number of coverings of $${\mathbb{C}P^1 {\setminus} \{0, 1, {\infty}\}}$$CP1\{0,1,∞} with a given monodromy type over $${\infty}$$∞ and given numbers of preimages of 0 and 1. We show
Geometry of Spectral Curves and All Order Dispersive Integrable System
We propose a definition for a Tau function and a spinor kernel (closely related to Baker{Akhiezer functions), where times parametrize slow (of order 1=N) deformations of an algebraic plane curve.
Identification of the Givental Formula with the Spectral Curve Topological Recursion Procedure
We identify the Givental formula for the ancestor formal Gromov–Witten potential with a version of the topological recursion procedure for a collection of isolated local germs of the spectral curve.
Formal pseudodifferential operators and Witten's r-spin numbers
We derive an effective recursion for Witten's r-spin intersection numbers, using Witten's conjecture relating r-spin numbers to the Gel'fand-Dikii hierarchy (Theorem 4.1). Consequences include
Cut-and-join description of generalized Brezin-Gross-Witten model
We investigate the Brezin-Gross-Witten model, a tau-function of the KdV hierarchy, and its natural one-parameter deformation, the generalized Brezin-Gross-Witten tau-function. In particular, we
Topological recursion for irregular spectral curves
All one-point invariants of the spectral curve $xy^2=1$ are calculated via a new three-term recursion for the number of dessins d'enfant with one face via topological recursion on the irregular spectral curve.
All-order asymptotics of hyperbolic knot invariants from non-perturbative topological recursion of A-polynomials
We propose a conjecture to compute the all-order asymptotic expansion of the colored Jones polynomial of the complement of a hyperbolic knot, J_N(q = exp(2u/N)) when N goes to infinity. Our
