Is anything known about the enumeration of degree d, genus g curves in CP^2 where g >1 ?

There is a combinatorial formula for the number of geometric genus $g$ curves of degree $d$ (possibly reducible) passing through $3d-1+g$ generic points of $\mathbb{P}^2$ (or a more general toric surf …

Has this generalization of a determinant (assigning multiplicities to the rows) been studied?

Summary There is a clear connection to the permanent, which, if I understand correctly, yields the same tropicalization, and a more speculative connection to the determinant. The reason is that OP's f …
