Abstract:We present several general results about drawings of urn:x-wiley:03649024:media:jgt21908:jgt21908-math-0003, as a beginning to trying to determine its crossing number. As application, we give a complete proof that the crossing number of K9 is 36 and that all drawings in one large, natural class of drawings of K11 have at least 100 crossings.
Keywords:crossing number  complete graph
