摘要：

Let gamma(G) be the domination number of a graph G, and let G x H be the direct product of graphs G and H. It is shown that for any k greater than or equal to 0 there exists a graph G such that gamma(G x C) less than or equal to gamma(G)(2) - k. This in particular disproves a conjecture from [5].
