Summary[edit]
| Description |
Français : Sous-graphe partiel du graphe des pays du monde reliés par une arête si ils sont limitrophes, montrant huit pays d'Eurasie et certaines de leurs frontières. Ce graphe est une expansion du graphe complet K5, ce qui prouve que le graphe des pays du monde n'est pas planaire par le théorème de Kuratowski. Cela est possible parce que le territoire de l'Azerbaïdjan n'est pas connexe : seule l'exclave de Nakhitchevan est limitrophe de la Turquie.
English: Subgraph of the graph of world countries where edges connect the countries which share a border, displaying eight Eurasian countries and some of their borders. This graph is a suvdivision of the complete graph K5, which proves that the graph of world countries is not planar due to Kuratowski's theorem. This is possible because Azerbaijan's territory is not connected: only the exclave of Nakhchivan borders Turkey. |
