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 $P^{1}$ to compute relations between Hodge integrals. We prov…

Computation of $λ$ -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 $g$ . These relations are obtained by computing the Poincaré-dual class of empty lo…
