The minimum number of intersections in complete graphs

Thomas Saaty
Journal: Proceedings of the National Academy of Sciences of the United States of America
Zarankiewicz has developed results concerning the minimum number of edge intersections, when drawn in a plane, of the bipartite graph consisting of two sets of vertices with one edge joining each element of one set to each element of the other set. When each set has three vertices, we have one of...

Two theorems on the minimum number of intersections for complete graphs

Thomas Saaty
Journal: Journal of Combinatorial Theory
After summarizing results of work on a conjecture regarding the minimum number of intersections of a complete graph drawn in the plane, the paper gives two theorems: one regarding a realization scheme for the conjectured quantity, and the other regarding a proof that essentially, the result would...

Remarks on the four color problem; the Kempe catastrophe

Thomas Saaty
Journal: Mathematics Magazine
The original error discovered by Heawood in Kempe's attempt to prove the four-color conjecture is often encountered by many of those who follow the inductive argument approach to the problem. Perhaps the nature of the difficulty is not well appreciated. An old Chinese proverb urges that to know t...

On polynomials and crossing numbers of complete graphs

Thomas Saaty
Journal: Journal of Combinatorial Theory
A long-standing, unsolved problem is that of finding the minimum number of crossings of the edges in a complete graph when embedded on a surface of genus zero.
