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…

On the large genus of Hurwitz numbers

Davide Accadia, Danilo Lewański, Giulio Ruzza

Hurwitz theory provides a large variety of enumerative problems related to algebraic geometry, mathematical physics, and combinatorics. We give a general framework to approach the…

On the combinatorics of the refined 1-leg DT/PT correspondence

Davide Accadia, Danilo Lewański, Sergej Monavari

We provide a new proof of a result of Bessenrodt on the relation among the generating series of reversed plane partitions and skew plane partitions, motivated by the geometric DT/P…

Les Houches lecture notes on moduli spaces of Riemann surfaces

Alessandro Giacchetto, Danilo Lewański

In these lecture notes, we provide an introduction to the moduli space of Riemann surfaces, a fundamental concept in the theories of 2D quantum gravity, topological string theory,…

The Spin Gromov-Witten/Hurwitz correspondence for

Alessandro Giacchetto, Reinier Kramer, Danilo Lewański +1

We study the spin Gromov-Witten (GW) theory of . Using the standard torus action on , we prove that the associated equivariant potential can be expresse…

On the strong DR/DZ equivalence conjecture

Xavier Blot, Danilo Lewanski, Sergey Shadrin

We establish the Miura equivalence of two integrable systems associated to a semi-simple cohomological field theory: the double ramification hierarchy of Buryak and the Dubrovin-Zh…
