Tropicalization of $\psi$ classes

Algebraic Geometry 2024-12-05 v1 Combinatorics

Abstract

Under suitable conditions on a family of logarithmic curves, we endow the tropicalization of the family with an affine structure in a neighborhood of the sections in such a way that the tropical ψ\psi classes from \cite{psi-classes} arise as tropicalizations of algebraic ψ\psi classes.
