| 1. | In particular, every planar graph has a planar arc diagram.
|
| 2. | For a planar graph, the crossing number is zero by definition.
|
| 3. | It is also a 3-non-planar graph.
|
| 4. | Of these graphs, the first four are planar graphs.
|
| 5. | The graph of eodermdrome is the non-planar graph K 5.
|
| 6. | Planar graphs generalize to graphs drawable on a surface of a given genus.
|
| 7. | For planar graphs, the branchwidth can be computed exactly in polynomial time.
|
| 8. | Apollonian networks are chordal maximal planar graphs, or equivalently planar 3-trees.
|
| 9. | Therefore, strangulated graphs include maximal planar graphs.
|
| 10. | It remains NP-complete for planar graphs.
