Improved bounds for the crossing numbers of Km,n and Kn
It has been long conjectured that the crossing number cr(Km,n) of the complete bipartite graph Km,n equals the Zarankiewicz number Z(m, n) :=[(m-1)/2][m/2][(n-1)/2][n/2]. Another longstanding conjecture states that the crossing number cr(Kn) of the complete graph Kn equals Z(n):=(1/4)[n/2][(n-1)/2][...
