用四个基本斜率绘制三次图

Drawing cubic graphs with the four basic slopes

Padmini Mukkamala, Dömötör Pálvölgyi

摘要:

我们证明了每一个三次图都可以只用四个基本斜率$\{0,π/4,π/2,3π/4\}$在平面上画出直线边。我们还证明了四个斜率具有这个性质当且仅当我们可以用它们画出$K_4$。

英文摘要:

We show that every cubic graph can be drawn in the plane with straight-line edges using only the four basic slopes $\{0,π/4,π/2,3π/4\}$. We also prove that four slopes have this property if and only if we can draw $K_4$ with them.
