Tropical correspondence for smooth del Pezzo log Calabi-Yau pairs

Consider a log Calabi-Yau pair ( X , D stretchy="false">) (X,D) consisting of smooth del Pezzo surface alttext="upper X"> encoding="application/x-tex">X degree alttext="greater-than-or-equal-to 3"> ? 3 encoding="application/x-tex">\geq 3 and anticanonical divisor D"> encoding="application/x-tex">D . We prove correspondence between genus zero logarithmic Gromov-Witten invariants intersecting in single point with maximal tangency the consistent wall structure appearing dual intersection complex from Gross-Siebert reconstruction algorithm. More precisely, logarithm product functions attached to unbounded walls gives generating function for these invariants.
