# Tropical images of intersection points

@article{Morrison2014TropicalIO, title={Tropical images of intersection points}, author={Ralph Morrison}, journal={Collectanea Mathematica}, year={2014}, volume={66}, pages={273-283} }

A key issue in tropical geometry is the lifting of intersection points to a non-Archimedean field. Here, we ask: where can classical intersection points of planar curves tropicalize to? An answer should have two parts: first, identifying constraints on the images of classical intersections, and, second, showing that all tropical configurations satisfying these constraints can be achieved. This paper provides the first part: images of intersection points must be linearly equivalent to the stable…
