Intersecting psi-classes on tropical Hassett spaces [PDF]

, 2022
We study the intersection of tropical \(\psi\)-classes on tropical heavy/light Hassett spaces, generalising a result of Kerber-Markwig for \(M^{\operatorname{trop}}_{0, n}\).

Polynomiality properties of tropical refined invariants [PDF]

, 2022
Tropical refined invariants of toric surfaces constitute a fascinating interpolation between real and complex enumerative geometries via tropical geometry.

Smooth Compactifications of the Abel-Jacobi Section

Forum of Mathematics, Sigma, 2023
For $\theta $ a small generic universal stability condition of degree $0$ and A a vector of integers adding up to $-k(2g-2+n)$ , the spaces $\overline {\mathcal {M}}_{g,A}^\theta $ constructed in [AP21, HMP+22] are observed to ...

Reproducibility of serum testing for environmental allergen‐specific IgE in dogs in Europe

Veterinary Dermatology, Volume 32, Issue 3, Page 251-e67, June 2021., 2021
Background – Serum testing for allergen‐specific immunoglobulin (Ig)E is commonly employed to identify allergens used for allergen‐specific immunotherapy in dogs, yet the reliability of results has been a matter of debate. Objective – The aim of this study was to evaluate the reproducibility of serum tests for environmental allergen‐specific IgE in ...

Tropically constructed Lagrangians in mirror quintic threefolds

Forum of Mathematics, Sigma, 2020
We use tropical curves and toric degeneration techniques to construct closed embedded Lagrangian rational homology spheres in a lot of Calabi-Yau threefolds. The homology spheres are mirror dual to the holomorphic curves contributing to the Gromov-Witten

k-leaky double Hurwitz descendants

Forum of Mathematics, Sigma
We define a new class of enumerative invariants called k-leaky double Hurwitz descendants, generalizing both descendant integrals of double ramification cycles and the k-leaky double Hurwitz numbers introduced in [CMR25].

Logarithmic Donaldson–Thomas theory

Forum of Mathematics, Pi
Let X be a smooth and projective threefold with a simple normal crossings divisor D. We construct the Donaldson–Thomas theory of the pair $(X|D)$ enumerating ideal sheaves on X relative to D.

A short proof of the multiple cover formula for point insertions

Forum of Mathematics, Sigma
A few years ago, G. Oberdieck conjectured a multiple cover formula that determines the number of curves of fixed genus and degree passing through a configuration of points in an abelian surface.

Expansions for Hilbert schemes of points on semistable degenerations

Forum of Mathematics, Sigma
The aim of this paper is to extend the expanded degeneration construction of Li and Wu to obtain good degenerations of Hilbert schemes of points on semistable families of surfaces, as well as to discuss alternative stability conditions and parallels to ...
