Demonstrates the emergence of tropical psi classes from algebraic psi classes through tropicalization of logarithmic curves, suggesting a new understanding of their structures.
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 classes from [6] arise as tropicalizations of algebraic ψ classes.
