Abstract(in Japanese) (See Japanese page)
Abstract(in English) Laplacian matrix is defined by node degrees and adjacency relationships between nodes in a graph, and it is useful to analyze graph structure of networks. Existing studies of Laplacian matrix clarified that the degree distribution of a network has a high similarity to the eigenvalue distribution of its Laplacian matrix. Since degree distribution only contains information of node degree, they did not clarify how the information of adjacency relationship affects the eigenvalues of Laplacian matrix. In our previous study, we analyzed the effect of adjacency relationship between nodes on eigenvalues of Laplacian matrix, but the strong dependence between the node degree and eigenvalue distributions intercepted our analysis. In this paper, we introduce Normalized Laplacian matrix, which Laplacian matrix normalized by node degrees, and experimentally investigate the effect of adjacency relationship between nodes on eigenvalues of Normalized Laplacian matrix.
