论文摘要
我们给出了恒定等级四边形的奇异铅笔的几何描述，将它们与$ \ mathbb {p}^1 $的某些天然相关矢量捆绑包的分裂类型联系起来。然后，我们在一般线性群体的自然作用下研究了它们的晶状体晶体轨道。
We give a geometric description of singular pencils of quadrics of constant rank, relating them to the splitting type of some naturally associated vector bundles on $\mathbb{P}^1$. Then we study their orbits in the Grassmannian of lines, under the natural action of the general linear group.
