Fundamental groups of some quadric-line arrangements

Meirav Amram, Mina Teicher, Muhammed Uludag

摘要:

本文给出了P^2中三个四元线排列的补的基本群的表示。第一种排列是一个光滑的二次曲面Q,有n条切线与Q相切,第二种排列是一个二次曲面Q,有n条直线通过不在Q中的点p。最后一种排列由一个二次曲面Q组成,其中n条直线通过Q中的一个点p。

英文摘要:

In this paper we obtain presentations of fundamental groups of the complements of three quadric-line arrangements in P^2. The first arrangement is a smooth quadric Q with n tangent lines to Q, and the second one is a quadric Q with n lines passing through a point p not in Q. The last arrangement consists of a quadric Q with n lines passing through a point p in Q.
