The moduli space of tropical curves with fixed Newton polygon

Desmond Coles, Neelav Dutta, Sifan Jiang, Ralph Morrison, Andrew Scharf

Published 2020-02-25Version 1

Given a lattice polygon, we study the moduli space of all tropical plane curves with that Newton polygon. We determine a formula for the dimension of this space in terms of combinatorial properties of that polygon. We prove that if this polygon is nonhyperelliptic or maximal and hyperelliptic, then this formula matches the dimension of the moduli space of nondegenerate algebraic curves with that given Newton polygon.
