Smooth toric refined Severi degree conjecture

About 12 years old · traced to

Let Δ\Delta be a convex lattice polygon, let S=X(Δ)S=X(\Delta) be the associated smooth toric surface, and let L=L(Δ)L=L(\Delta) be a δ\delta-very ample line bundle. Let NΔ,δ(y)N^{\Delta,\delta}(y) be the tropical refined Severi degree and N~(S,L),δ(y)\widetilde N^{(S,L),\delta}(y) the refined universal invariant. Smooth toric refined Severi degree conjecture.

NΔ,δ(y)=N~(S,L),δ(y).N^{\Delta,\delta}(y)=\widetilde N^{(S,L),\delta}(y).

The paper proves this comparison for several basic toric surfaces and leaves the general smooth toric case conjectural.
