Abstract

Crossing numbers of graphs are in general very difficult to compute. There are several known exact results on the crossing number of the Cartesian products of paths, cycles or stars with small graphs. In this paper we study cr(Km □ Pn), the crossing number of the Cartesian product Km □ Pn. We prove that $$cr(K_{m} \square P_n)\leq \frac{1}{4}\lfloor\frac{m+1}{2}\rfloor\lfloor\frac{m-1}{2} \rfloor\lfloor\frac{m-2}{2}\rfloor(n\lfloor\frac{m+4}{2} \rfloor+ \lfloor\frac{m-4}{2}\rfloor)$$ for m ≥ 3,n ≥ 1 and cr(Km □ Pn)≥ (n − 1)cr(Km+2 − e) + 2cr(Km+1). For m≤ 5, according to Klesc, Jendrol and Scerbova, the equality holds. In this paper, we also prove that the equality holds for m = 6, i.e., cr(K6 □ Pn) = 15n + 3.

Abstract

The multicolor Ramsey number R r (H) is defined to be the smallest integer n=n(r) with the property that any r-coloring of the edges of the complete graph K n must result in a monochromatic subgraph of K n isomorphic to H. It is well known that 2 r m
