A new proof of 3-colorability of Eulerian triangulations

Mu-Tsun Tsai, Douglas B. West

Abstract


Using the existence of noncrossing Eulerian circuits in Eulerian plane graphs, we give a short constructive proof of the theorem of Heawood that Eulerian triangulations are 3-colorable.

Keywords


Plane triangulation, Eulerian circuit, 3-colorable, Heawood's Theorem
