摘要
We determine the values of s and t for which there is a coloring of the edges of the complete bipartite graph K-s,K-t which admits only the identity automorphism. In particular, this allows us to determine the distinguishing number of the Cartesian product of complete graphs. (C) 2007 Elsevier B.V. All rights reserved.
