实Cayley M-八元组的形变类
Deformation classes of real Cayley M-octads
摘要:
研究了实射影空间中三个二次曲面相交轨迹不含共面四元曲面的8点构形。我们发现,正好存在8个镜像对的变形类的这种配置。我们还描述了这8对的相互位置,并找到真正的单值群作用于8点配置,为每个变形类。
英文摘要:
We study 8-point configurations in the real projective space forming an intersection locus of three quadrics and containing no coplanar quadruples. We found that there exists precisely 8 mirror-pairs of deformation classes of such configurations. We describe also the mutual position of these 8 pairs and find the real monodromy groups acting on the 8-point configurations, for each deformation class.
