总结了图与复杂网络(包括随机图与小世界网络)的拉普拉斯谱的最新的结果和研究进展.主要内容包括给定度序列的拉普拉斯谱半径、拉普拉斯系数、代数连通度、双随机矩阵和随机图与小世界网络的谱的性质.并且提出了可能进一步研究的一些相关的问题.
A brief survey of some recent new results and progress of the Laplacian spectra of graphs and complex networks(in particular,random graph and the small world network)was presented.The main contents contain the spectral radius of the graph Laplacian for a given degree sequence,the Laplacian coefficients,the algebraic connectivity and the graph doubly stochastic matrix,and the spectra of random graphs and the small world networks.In addition,some questions were proposed.
