Effect of leaf nodes on synchronizability of complex networks

The synchronizability of the complex network has aroused much interest during the past years. But most studies pay little attention to the leaf nodes （whose degree equals 1），which do exist in the real networks. In this paper，we study the influence of leaf nodes on the synchronizability of the whole network systematically and find that as the proportion of the leaf nodes increases，the network becomes less synchronizable. Both numerical and theoretical results are given in the paper.
