Ralph Morrison, Lucas Tolley
In the theory of divisors on multigraphs, the divisorial gonality of a graph is the minimum degree of a rank divisor on that graph. It was proved by Gijswijt et al. th…

Tropical Images of Intersection Points
Ralph Morrison
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 tropicaliz…
