摘要

我们完成了一个定理的证明，我们在[数学]中宣布并部分证明了它。数学学报，2004,69-90，数学. ag /0111299。这个定理涉及曲面族上的曲线族。它有两部分。第一个在那篇论文中得到了证明。它描述了一个自然循环，枚举族中恰好有$r$普通节点的曲线。第二部分在此得到证明。证明了对于r\le 8$，这个循环的类是由族的陈氏类的积的参数空间的压下中的一个可计算的普适多项式给出的。

Node Polynomials for Curves on Surfaces

We complete the proof of a theorem we announced and partly proved in [Math. Nachr. 271 (2004), 69-90, math.AG/0111299]. The theorem concerns a family of curves on a family of surfaces. It has two parts. The first was proved in that paper. It describes a natural cycle that enumerates the curves in the family with precisely $r$ ordinary nodes. The second part is proved here. It asserts that, for $r\le 8$, the class of this cycle is given by a computable universal polynomial in the pushdowns to the parameter space of products of the Chern classes of the family.
