Sekundarni naslov: | Properties of Laplacian matrices of simple and mixed graphs |
Sekundarni povzetek: | In this work we discuss the spectral theory of simple and mixed graphs. For the Laplacian matrix of a simple graph we show that the multiplicity of the eigenvalue zero equals the number of connected components of the graph and we examine integer eigenvalues of the Laplacian matrix of a tree. For a mixed graph we show that the Laplacian matrix of a quasi-bipartite graph has the same spectrum as the Laplacian matrix of the corresponding underlying simple graph. We present the classification of all nonsingular connected mixed graphs on at least seven vertices whose Laplacian matrices have exactly two eigenvalues greater than two. |
