# Intersecting $\psi$-classes on $M_{0,w}^{\mathrm{trop}}$

@inproceedings{Hahn2021IntersectingO, title={Intersecting \$\psi\$-classes on \$M\_\{0,w\}^\{\mathrm\{trop\}\}\$}, author={Marvin Anas Hahn and Shiyue Li}, year={2021} }

In this paper, we study the intersection products of weighted tropical ψ-classes, in arbitrary dimensions, on the moduli space of tropical weighted stable curves. We introduce the tropical Gromov–Witten multiplicity at each vertex of a given tropical curve. This concept enables us to prove that the weight of a maximal cone in an intersection of ψ-classes decomposes as the product of tropical Gromov–Witten multiplicities at all vertices of the cone’s associated tropical curves. Along the way, we…

A tropical analogue of Hassett's moduli spaces of weighted stable curves is defined and it is shown that the naive set-theoretic tropicalization map can be identified with a natural deformation retraction onto the non-Archimedean skeleton.

The diagonal of tropical matroid varieties and cycle intersections

We define an intersection product of tropical cycles on matroid varieties (via cutting out the diagonal) and show that it is well-behaved. In particular, this enables us to intersect cycles on moduli…
