Abstract
Consider the Fulton-MacPherson configuration space of n points on ℙ1, which is isomorphic to a certain moduli space of stable maps to ℙ1. We compute the cone of effective n-invariant divisors on this space. This yields a geometric interpretation of known asymptotic formulas for the number of integral points of bounded height on compactifications of SL2 in the space of binary forms of degree n≥3
