设S是非奇异射影K-平凡曲面,V是S上秩为s的向量丛。我们计算了S中n个点的Hilbert概型上重言丛的顶塞格雷类。在秩s=1的情况下,我们的结果专门化到Lehn以前所证明的公式。
Let S be a nonsingular projective K-trivial surface, and let V be a vector bundle on S of rank s. We calculate the top Segre class of the tautological bundle over the Hilbert scheme of n points of S associated to V. In the rank s=1 case, our result specializes to Lehn's previously conjectured formula.
