论文摘要
在本说明中，我们给出了惠特尼定理的更一般版本的简短和基本证明，即三个连接的平面图在飞机上具有独特的嵌入。定理的结果是，与简单双重的二级法无法嵌入更高的属中。本文的目的是促进简单而基本的证据，这特别适合介绍惠特尼定理的讲座。
In this note we give a short and elementary proof of a more general version of Whitney's theorem that 3-connected planar graphs have a unique embedding in the plane. A consequence of the theorem is that cubic plane graphs cannot be embedded in a higher genus with a simple dual. The aim of this paper is to promote a simple and elementary proof, which is especially well suited for lectures presenting Whitney's theorem.
