Distinguishing colorings of Cartesian products of complete graphs

Combinatorics 2007-05-23 v1

Abstract

We determine the values of s and t for which there is a coloring of the edges of the complete bipartite graph K_{s,t} which admits only the identity automorphism. In particular this allows us to determine the distinguishing number of the Cartesian product of complete graphs.
