A prismatic Riemann-Hilbert correspondence
Dylan Pentland
We study the category of constructible -Kummer-étale sheaves on the log adic generic fiber for the stratification induced by a horizont…
A new spin on polynomial relations among kappa classes
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We prove a recent conjecture of the fourth named author with P. Norbury that states a system of universal polynomial relations among the kappa classes on the moduli spaces of algeb…
Blobbed topological recursion and KP integrability
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We revise the notion of the blobbed topological recursion by extending it to the setting of generalized topological recursion as well as allowing blobs which do not necessarily adm…
KP integrability of non-perturbative differentials
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We prove the KP integrability of non-perturbative topological recursion, which can be considered as a formal -deformation of the Krichever construction of algebro-geometric…
Degenerate and irregular topological recursion
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We use the theory of duality to propose a new definition / construction for the correlation differentials of topological recursion; we call it "generalized topological recurs…
Any topological recursion on a rational spectral curve is KP integrable
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We prove that for any initial data on a genus zero spectral curve the corresponding correlation differentials of topological recursion are KP integrable. As an application we prove…
Symplectic duality via log topological recursion
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We review the notion of symplectic duality earlier introduced in the context of topological recursion. We show that the transformation of symplectic duality can be expressed as a c…
Log topological recursion through the prism of swap
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We introduce a new concept of logarithmic topological recursion that provides a patch to topological recursion in the presence of logarithmic singularities and prove that this new…
KP integrability through the swap relation
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We discuss a universal relation that we call the swap relation, which plays a prominent role in the theory of topological recursion, Hurwitz theory, and free probability theo…
Topological recursion, symplectic duality, and generalized fully simple maps
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
For a given spectral curve, we construct a family of symplectic dual spectral curves for which we prove an explicit formula expressing the -point functions produced by the topol…
A universal formula for the swap in topological recursion
Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2
We prove a recent conjecture of Borot et al. that a particular universal closed algebraic formula recovers the correlation differentials of topological recursion after the swap of…
Symplectic duality for topological recursion
Boris Bychkov, Petr Dunin-Barkowski, Maxim Kazarian +1
We consider weighted double Hurwitz numbers, with the weight given by arbitrary rational function times an exponent of the completed cycles. Both special singularities are arbitrar…
Electrical Networks, Lagrangian Grassmannians and Symplectic Groups
Boris Bychkov, Vassily Gorbounov, Anton Kazakov +1
We refine the result of T. Lam \cite{L} on embedding the space of electrical networks on a planar graph with boundary points into the totally non-negative Grassmannian $\…
Generalised ordinary vs fully simple duality for -point functions and a proof of the Borot--Garcia-Failde conjecture
Boris Bychkov, Petr Dunin-Barkowski, Maxim Kazarian +1
We study a duality for the -point functions in VEV formalism that we call the ordinary vs fully simple duality. It provides an ultimate generalisation and a proper context for t…
Topological recursion for Kadomtsev-Petviashvili tau functions of hypergeometric type
Boris Bychkov, Petr Dunin-Barkowski, Maxim Kazarian +1
We study the -point differentials corresponding to Kadomtsev-Petviashvili tau functions of hypergeometric type (also known as Orlov-Scherbin partition functions), with an emphas…
Explicit closed algebraic formulas for Orlov-Scherbin -point functions
Boris Bychkov, Petr Dunin-Barkowski, Maxim Kazarian +1
We derive a new explicit formula in terms of sums over graphs for the -point correlation functions of general formal weighted double Hurwitz numbers coming from the Kadomtsev-Pe…
Functional Relations on Anisotropic Potts Models: from Biggs Formula to the Tetrahedron Equation
Boris Bychkov, Anton Kazakov, Dmitry Talalaev
We explore several types of functional relations on the family of multivariate Tutte polynomials: the Biggs formula and the star-triangle () transformation at the critical poi…
Combinatorics of Bousquet-Mélou-Schaeffer numbers in the light of topological recursion
Boris Bychkov, Petr Dunin-Barkowski, Sergey Shadrin
In this paper we prove, in a purely combinatorial way, a structural quasi-polynomiality property for the Bousquet-Mélou-Schaeffer numbers. Conjecturally, this property should follo…
Degrees of cohomological classes of multisinguliarities in Hurwitz spaces of rational functions
Boris Bychkov
The main goal of the present paper are new formulae for degrees of strata in Hurwitz spaces of rational functions having two degenerate critical values with preimages of prescribed…
On the number of coverings of the sphere ramified over given points
Boris Bychkov
We present the generating function for the numbers of isomorphism classes of coverings of the two-dimensional sphere by the genus compact oriented surface not ramified outside…
