In 1973, Kronk and Mitchem (Discrete Math. (5) 255-260) conjectured that the vertices, edges and faces of each plane graph G may be colored with D(G) + 4 colors, where D(G) is the maximum degree of G, so that any two adjacent or incident elements receive distinct colors. They succeeded in verifying

If in a plane graph with minimum degree 2 3 no t w o triangles have an edge in common, then: (1 there are two adjacent vertices with degree sum at most 9, and (2) there is a face of size between 4 and 9 or a 10-face incident with ten 3-vertices. It follows that every planar graph without cycles betw
The strength of a point in a graph is defined as the increase in the number of connected components in the graph upon removal of the point. Given an ordering of the points of a graph, the strength vector S of the graph is the vector whose ith component is the strength of the ith point of the graph.
