Spin volumes of minimal strata and Chiodo integrals
Andrei Bud, Georgios Politopoulos, Stijn Velstra
We derive a closed formula for the Masur-Veech volumes of spin-parity components of the stratum of abelian differentials with a single zero of maximal order. Our approach is based…
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…
Relations for quadratic Hodge integrals via stable maps
Georgios Politopoulos
Following Faber-Pandharipande, we use the virtual localization formula for the moduli space of stable maps to to compute relations between Hodge integrals. We prov…
Computation of -classes via strata of differentials
Georgios Politopoulos, Adrien Sauvaget
We introduce a new family of tautological relations of the moduli space of stable curves of genus . These relations are obtained by computing the Poincaré-dual class of empty lo…
