Abstract:Investigation of the crossing number of graphs is a classical but very difficult problem. The exact value of the crossing number is known only for a few specific families of graphs. In this paper we extend a recent result from Bokal on the crossing number of K(1,m)square P(n), and prove that cr(K(2,m)square P(n)) = 2n left perpendicular m/2 right perpendicular left perpendicular m-1/2 right perpendicular.
