我们首先给出了一个替代的证明,基于一个简单的几何参数,结果玛丽安,Oprea和Pandharipande的顶部塞格雷类重言式丛希尔伯特计划的$K3$曲面配备了一个线丛。然后,我们转向$K3$曲面在一个点的爆破,并建立相应的顶部塞格雷类在一定范围内消失的结果。这至少在理论上决定了任何对$(\Sigma,H),\,H\in {\rm Pic}\,\Sigma$的重言丛的所有顶塞格雷类。
We first give an alternative proof, based on a simple geometric argument, of a result of Marian, Oprea and Pandharipande on top Segre classes of the tautological bundles on Hilbert schemes of $K3$ surfaces equipped with a line bundle. We then turn to the blow-up of $K3$ surface at one point and establish vanishing results for the corresponding top Segre classes in a certain range. This determines, at least theoretically, all top Segre classes of tautological bundles for any pair $(\Sigma,H),\,H\in {\rm Pic}\,\Sigma$.
