摘要

我们研究了某些阶数为 7 的圆锥曲线排列的嵌入拓扑学。我们给出了扎里斯基对的两个新例子。此外，我们还确定了圆锥曲线排列的连接成分数。我们还在附录中使用 SageMath 和软件包 Sirocco 计算了基本群。

The realization spaces of certain conic-line arrangements of degree 7

We study the embedded topology of certain conic-line arrangements of degree 7. Two new examples of Zariski pairs are given. Furthermore, we determine the number of connected components of the conic-line arrangements. We also calculate the fundamental groups using SageMath and the package Sirocco in the appendix.
