Using the Entropy of the DFT of the Laplacian Eigenvalues to Assess Networks

چکیده
There are several metrics that are very useful to analyze and to design networks. These metrics, including the spectral-based ones, can be used to retrieve topological properties from the network. We observed that if one applies the Discrete Fourier Transform (DFT) over the eigenvalues of the Laplacian matrix, it is possible to observe different patterns in the DFT depending on some properties of the analyzed networks. In this paper, we propose a new metrics based on the entropy of the DFT samples, that can be used to identify the type of network. We evaluated this metrics in networks generated by four different procedures (k-Regular, ErdosRenyi, Watts-Strogatz and Barabasi-Albert) and in well-known datasets of real networks. The results indicate that one can use the proposed metrics to identify the generational model of the network.

Seidel Signless Laplacian Energy of Graphs
Let $S(G)$ be the Seidel matrix of a graph $G$ of order $n$ and let $D_S(G)=diag(n-1-2d_1, n-1-2d_2,ldots, n-1-2d_n)$ be the diagonal matrix with $d_i$ denoting the degree of a vertex $v_i$ in $G$. The Seidel Laplacian matrix of $G$ is defined as $SL(G)=D_S(G)-S(G)$ and the Seidel signless Laplacian matrix as $SL^+(G)=D_S(G)+S(G)$. The Seidel signless Laplacian energy $E_{SL^+...
متن کاملLaplacian Energy of a Fuzzy Graph
A concept related to the spectrum of a graph is that of energy. The energy E(G) of a graph G is equal to the sum of the absolute values of the eigenvalues of the adjacency matrix of G . The Laplacian energy of a graph G is equal to the sum of distances of the Laplacian eigenvalues of G and the average degree d(G) of G. In this paper we introduce the concept of Laplacian energy of fuzzy graphs. ...

Let $G$ be a graph without an isolated vertex, the normalized Laplacian matrix $tilde{mathcal{L}}(G)$ is defined as $tilde{mathcal{L}}(G)=mathcal{D}^{-frac{1}{2}}mathcal{L}(G)mathcal{D}^{-frac{1}{2}}$, where $mathcal{D}$ is a diagonal matrix whose entries are degree of vertices of $G$.
