A new family of weighted double Hurwitz numbers and a new ELSV-type formula with -classes

Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2

We analyze a new family of weighted double Hurwitz numbers that was introduced as a notable example in the context of the duality for logarithmic topological recursion. We us…

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…
