Triple Hodge integrals and constant Poisson brackets for rank-one Dubrovin-Zhang hierarchies

Xavier Blot, Guido Carlet, Dimitrios Makris +1

We prove a conjecture of Dubrovin, Liu, Yang, and Zhang that states that the Poisson bracket of the Dubrovin-Zhang hierarchy of a rank-one cohomological field theory is constant if…

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…

Beyond descendants: integrable observables for cohomological field theories

Xavier Blot, Danilo Lewański, Sergey Shadrin

We introduce the concept of integrable observables and propose them as alternatives to the standard Witten's psi classes (a.k.a. descendants in quantum gravity) to be coupled…

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…

The quantum integrable hierarchy for the Gromov-Witten theory of elliptic curves

Paolo Rossi, Sergey Shadrin, Ishan Jaztar Singh

We construct the quantum double ramification hierarchy associated with the Gromov-Witten theory of elliptic curves. We use results of Oberdieck and Pixton on the intersection numbe…

Taking limits in topological recursion

Gaëtan Borot, Vincent Bouchard, Nitin Kumar Chidambaram +2

When does topological recursion applied to a family of spectral curves commute with taking limits? This problem is subtle, especially when the ramification structure of the spectra…
