I will discuss applications of tropical geometry for studying general line bundles on general curves. As observed by Wahl, a curve may be embedded in a K3 surface only when a certain map, now known as the Wahl map, is not surjective.
The more general Gauss–Wahl map provides an intrinsic criterion for
embeddability in other surfaces. I will explain how these maps can be studied by appealing to Berkovich skeletons, and discuss ongoing work towards proving surjectivity in high genus.
This is joint work with Dave Jensen.
