A simple and elementary proof of Whitney's unique embedding theorem

Gunnar Brinkmann


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 also 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.
