Intersecting Psiclasses on tropical M_{0,n}
Abstract
We apply the tropical intersection theory developed by L. Allermann and J. Rau to compute intersection products of tropical Psiclasses on the moduli space of rational tropical curves. We show that in the case of zerodimensional (stable) intersections, the resulting numbers agree with the intersection numbers of Psiclasses on the moduli space of nmarked rational curves computed in algebraic geometry.
