An intersection-theoretic proof of the Harer-Zagier formula
Alessandro Giacchetto, Danilo Lewański, Paul Norbury
We provide an intersection-theoretic formula for the Euler characteristic of the moduli space of smooth curves. This formula reads purely in terms of Hodge integrals and, as a coro…
On some hyperelliptic Hurwitz-Hodge integrals
Danilo Lewański
This short note addresses Hodge integrals over the hyperelliptic locus. Recently Afandi computed, via localisation techniques, such one-descendant integrals and showed that they ar…
A natural basis for intersection numbers
Bertrand Eynard, Danilo Lewański
We advertise elementary symmetric polynomials as the natural basis for generating series of intersection numbers of genus g and n marked points. Closed formulae for…
A new spin on Hurwitz theory and ELSV via theta characteristics
Alessandro Giacchetto, Reinier Kramer, Danilo Lewański
We study spin Hurwitz numbers, which count ramified covers of the Riemann sphere with a sign coming from a theta characteristic. These numbers are known to be related to Gromov-Wit…
