Tropical moduli spaces of rational graphically stable curves
Speaker: Andy Fry (Colorado State University)
Speaker's URL: https://www.math.colostate.edu/~fry/
Abstract: The tropical moduli space $M_{0,n}^{trop}$ is a cone complex which parameterizes leaf-labelled metric trees called tropical curves. Separately, Tevelev, and Gibney and Maclagan show that $M_{0,n}^{trop}$ is the geometric tropicalization of the classical moduli space of pointed curves $M_{0,n}$. In this talk, I will introduce a new stability condition on the moduli space given by the combinatorics of a graph $\Gamma$. I will also show that when $\Gamma$ is a complete multipartite graph, the tropical moduli space $M_{0,\Gamma}^{trop}$ is the geometric tropicalization of its classical counterpart $M_{0,\Gamma}$.
