Some Results on Crossing Numbers

Abstract

dc:description.abstract

The drawing of the complete graph in which the vertices are placed on the rims of a cylinder and connected with geodesic edges is conjectured to produce the minimum number of edge crossings for a complete graph, which is its crossing number. This dissertation proves that no edge in this drawing can be redrawn to reduce the total number of edge crossings.
