For example, if G is a complete graph, it is clear that G contains every tree having n -1 edges(i.e., the conjecture is true in this case) , since G satisfies m =n(n -1)/2 and k≦n -1, and there is an edge (u,v) for any two vertices u,v E G(u ≠ v). Furthermore, some partial results have been obtained in other special cases. However, this conjecture is still open in general graphs satisfying m>n(k-1)/2. In this paper, we prove that the conjecture is true in regular graphs and in complete bipartite graphs.
