Points in special position for tropical curves

From CRCG-Wiki

In this talk, we reveal structural aspects of tropical enumerative geometry which are not just the analog of classical facts.

Consider the moduli space of rational -marked tropical curves of given degree in . We define for these curves the set of points in special position in two non-equivalent ways and discover that both of these sets have the structure of a tropical fan in . We describe these fans in explicit terms including their weights.

This is joint work with Andreas Gathmann.
