摘要:The small-world network, proposed by Watts and Strogatz, has beenextensively studied for the past over ten years. In this report, a generalized small-world network  is proposed, which extends several

small-world network models. Further, some properties of thegeneralized small-world network, such as the degree distribution andthe isoperimetric number, have been investigated. These results areused to present a lower and an upper bounds for the clustercoefficient and the diameter of the generalized small-world network,respectively. In other words, we prove mathematically that thesmall-world network possesses large clustering coefficient and smalldiameter. ( This work is jointed with Lei Gu and Huilin Huang )
