该研究针对正交格拉斯曼簇的希尔伯特概型,确定其连通分支数与内法锥,推广了Seong关于普通格拉斯曼簇的结论,所用方法结合了其证明技术与舒伯特演算。
AI 中文摘要
我们证明了在特定条件下正交格拉斯曼簇的希尔伯特概型的连通分支数,并利用该结果描述希尔伯特概型的几何性质。随后,通过确定与它的内龙-塞维里群生成元对偶的曲线,我们确定了该希尔伯特概型的内法锥。我们的结果推广了Seong关于普通格拉斯曼簇的结论,方法上采用了他的证明技术及相关舒伯特演算。
英文摘要
We show the number of connected components of the Hilbert scheme of orthogonal Grassmannians under certain condition, and use this result to describe the geometry of the Hilbert scheme. Subsequently, we determine the Nef cone of the Hilbert scheme by identifying curves dual to the generators of its Neron-Severi group. Our results generalize those of ordinary Grassmannians by Seong, and our approach adapts his proof technique alongside relevant Schubert calculus.
