Topological recursion for MasurâVeech volumes
arXiv DOIAbstract
We study the MasurâVeech volumes of quadratic differentials, showing they correspond to constant terms of polynomials determined by topological recursion/Virasoro constraints.
MasurâVeech volumes and intersection theory, the principal strata of quadratic differentials
arXiv DOIAbstract
We prove that the descendant integrals of the Segre class of the quadratic Hodge bundle are computed by topological recursion.
On the Kontsevich geometry of the combinatorial TeichmĂźller space
arXivAbstract
We study the geometry of the combinatorial moduli spaces, providing a completely geometric proof of Wittenâs conjecture.
A new spin on Hurwitz theory and ELSV via theta characteristics
arXivAbstract
We study spin Hurwitz numbers, which count ramified covers of the Riemann sphere with a sign coming from a theta characteristic. We conjecture a topological recursion governing these counts, and prove equivalence with an ELSV formula.
Around the combinatorial unit ball of measured foliations on bordered surfaces
arXiv DOIAbstract
We study the \(L^p\)-integrability of the volume of the unit ball in the space of measured foliations.
An intersection-theoretic proof of the HarerâZagier formula
arXiv DOIAbstract
We compute the Euler charcteristic of the moduli space of curves via ChernâGaussâBonnet and Hodge integrals.
Shifted Witten classes and topological recursion
arXiv DOIAbstract
We deduce Wittenâs \(r\)-spin conjecture from the connection between Giventalâs formalism and topological recursion.
Relations on \({\overline{\mathcal{M}}}_{g,n}\) and the negative \(r\)-spin Witten conjecture
arXiv DOIAbstract
We construct a negative \(r\)-spin cohomological field theory, the \(r\)-spin \({\Theta}\)-class, prove topological recursion and \({\mathcal{W}}\)-constraints, and derive tautological relations via Telemanâs classification.
The spin GromovâWitten/Hurwitz correspondence for \({\mathbb{P}}^1\)
arXiv DOIAbstract
We prove the GW/H correspondence for the spin projective line, a first step toward the computation of GW invariants of surfaces of general type.
Resurgent large genus asymptotics of intersection numbers
arXivAbstract
We prove the large genus asymptotics for WittenâKontsevich, Norburyâs, and \(r\)-spin intersection numbers.
Length spectrum of large genus random metric maps
arXiv DOIAbstract
We prove that the lenght spectrum of random metric maps converges to a Poisson point process in the large genus limit.
Symmetries of F-cohomological field theories and F-topological recursion
arXiv DOIAbstract
We introduce F-topological recursion and show that the descendant theory of F-CohFTs in the Givental orbit are compute by F-topological recursion.
Can transformers do enumerative geometry?
arXiv Open access CodeAbstract
We use transformer to compute and understand recursive patterns in \(\psi\)-class intersection numbers, showing that the model learns key mathematical features from the data.
The factorial growth of topological recursions
arXiv DOIAbstract
We prove that topological recursion is Gevrey-2.
Les Houches lecture notes on moduli spaces of Riemann surfaces
arXiv Open accessAbstract
Lecture notes on the moduli space of curves, cohomological field theories, and topological recursion.
Theta classes: generalized topological recursion, integrability and \({\mathcal{W}}\)-constraints
arXivAbstract
We introduce a new collection of CohFTs, the \({\Theta}^{r,s}\)-classes, and show that their descendant potential is an \(r\)-KdV tau function, is computed by topological recursion, and satisfies \({\mathcal{W}}\)-constraints.

Riemann Surfaces
Undergraduate course, ETHZ, Spring 2024
A first introduction to the theory of Riemann surfaces. These are beautiful objects that sit at the intersection of algebra, geometry, and analysis. We covered the theorems of RiemannâHurwitz, RiemannâRoch, and AbeliâJacobi, as well as the basics of Hurwitz theory.
Toric Geometry
Undergraduate course, ETHZ, Spring 2025
Toric varieties provide a rich class of examples in algebraic geometry that bridge combinatorics and geometry, making them an ideal starting point for exploring the interplay between these fields. We will introduce toric varieties, study their combinatorial and abstract structures, and examine their basic geometry, including Picard groups, cohomology, and singularities.
