Spectra of Some Simple Graphs

Abstract

We consider a finite undirected and connected simple graph  with vertex set  and edge set . The spectra of some special simple graphs and different types of their matrices are discussed to represent a graph. In this discussion we are interested in the adjacency matrix, Laplacian matrix, signless Laplacian matrix, normalized Laplacian matrix, and seidel adjacency matrix.

Keywords: Laplacian matrix, signless Laplacian matrix, normalized Laplacian matrix, seidel adjacency matrix, spectral.
