Chow quotients of toric varieties as moduli of stable log maps

##### Abstract

Let $X$ be a projective normal toric variety and ${T}_{0}$ a rank-$1$ subtorus of the defining torus $T$ of $X$. We show that the normalization of the Chow quotient $X∕∕{T}_{0}$, in the sense of Kapranov, Sturmfels, and Zelevinsky, coarsely represents the moduli space of stable log maps to $X$ with discrete data given by ${T}_{0}\subset X$. We also obtain similar results when ${T}_{0}\to T$ is a homomorphism that is not necessarily an embedding.
