Planar Graphs - SlideServe

A planar graph G is said to be completely regular if the degrees of all vertices of G are equal and every region is bounded by the same number of edges. The graphs in Figs. 2-20(a) and 2-21(b) are completely regular, for example. Show that there are only five possible simple completely regular planar graphs, excluding the trivial graphs with degree ≤2. Sketch them. | Numerade

A planar graph G is outerplanar if G can be drawn in the plane so that all of its vertices lie on the exterior boundary. (i) Show that K4 and K2,3 are not outerplanar. (ii) Deduce that, if G is an outerplanar graph, then G contains no subgraph homeomorphic or contractible to K4 or K23. (The converse result also holds, yielding a Kuratowski-type criterion for a graph to be outerplanar.) | Numerade
