On 3-colorings of Plane Graphs

Acta Mathematicae Applicatae Sinica, English Series, 2004
The main result of the paper states that any \(3\)-colouring of the vertices of a face of degree at least \(11\) in a planar graph \(G\) without cycles of length \(4\), \(5\) and \(7\) and with no pair of intersecting triangles (i.e. every two 3-cycles of \(G\) are vertex-disjoint) can be extended to a \(3\)-colouring of the whole graph \(G\).

Planar and Plane Graphs

1992
Planar graphs have many important applications in computer science, for example in VLSI layout. Many problems that are hard or even NP-complete for arbitrary graphs are much easier for planar graphs. In the next lecture we will prove a nice result due to Lipton and Tarjan in 1977 [73] which opens up planar graphs to divide-and-conquer.

Drawing Plane Graphs

2003
Automatic aesthetic drawing of plane graphs has recently created intense interest due to its broad applications, and as a consequence, a number of drawing methods, such as the straight line drawing, convex drawing, orthogonal drawing, rectangular drawing and box-rectangular drawing, have come out [8,9,3,4,5,6,7, 10,11,14,16,23,29,33].
