✦ Synopsis


Our main result is that a 1971 conjecture due to Paul Kainen is false. Kainen's conjecture implies that the genus 2 crossing number of K 9 is 3. We disprove the conjecture by showing that the actual value is 4. The method used is a new one in the study of crossing numbers, involving proof of the impossibility of certain genus 2 embeddings of Ks.

## Abstract The crossing number of __K~n~__ is known for __n__ ⩽ 10. We develop several simple counting properties that we shall exploit in showing by computer that __cr__(__K__~11~ = 100, which implies that __cr__(__K__~12~) = 150. We also determine the numbers of non‐isomorphic optimal drawings o

We introduce a general framework to estimate the crossing number of a graph on a compact 2-manifold in terms of the crossing number of the complete graph of the same size on the same manifold. The bounds are tight within a constant multiplicative factor for many graphs, including hypercubes, some co
