正多边形对角线的交点数

The Number of Intersection Points Made by the Diagonals of a Regular Polygon

Bjorn Poonen, Michael Rubinstein

摘要:

本文给出了正则$n$ -边形的对角线所构成的内交点的个数公式。答案是每个剩余类模2520的多项式。我们还计算区域的数量形成的对角线,通过使用欧拉公式$V-E+F=2$。

英文摘要:

We give a formula for the number of interior intersection points made by the diagonals of a regular $n$-gon. The answer is a polynomial on each residue class modulo 2520. We also compute the number of regions formed by the diagonals, by using Euler's formula $V-E+F=2$.
