Sign-reversing involutions in moduli spaces of curves
Sign-reversing involutions yield explicit formulas for psi-class intersections on multicolored genus-zero moduli spaces of curves and show that the tropical Euler characteristic analog for graphical spaces with two dominant vertices equals the number of acyclic orientations of the graph minus those
