Virtual volumes of strata of meromorphic differentials with simple poles

Adrien Sauvaget

We work over strata of meromorphic differentials with poles of order 1, and on affine subspaces defined by linear conditions on the residues. We propose a definition of the volume…

Meromorphic differentials and twisted DR hierarchies for the Hodge CohFT

Xavier Blot, Paolo Rossi, Adrien Sauvaget

In [arXiv:2408.13806], two families of classical and quantum integrable hierarchies associated to arbitrary Cohomological Field Theories (CohFTs) were introduced: the meromorphic d…

DR cycles and strata of differentials with spin parity

David Holmes, Georgios Politopoulos, Adrien Sauvaget

We study classes of strata of differentials with fixed spin parity in the Chow ring of moduli spaces of curves. We show that these classes are tautological and computable. Furtherm…

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…

Integrals of -classes on twisted double ramification cycles and spaces of differentials

Matteo Costantini, Adrien Sauvaget, Johannes Schmitt

We prove a closed formula for the integral of a power of a single -class on strata of -differentials. In many cases, these integrals correspond to intersection numbers on tw…

The master relation for polynomiality and equivalences of integrable systems

Xavier Blot, Adrien Sauvaget, Sergey Shadrin

We prove the so-called master relation in the tautological ring of the moduli space of curves that implies polynomial properties of the Dubrovin-Zhang hierarchies associated to dif…
