Properties of the characteristic polynomials and spectrum of Pn and Cn
Keywords:Laplacian Matrix, Signless Laplacian Matrix, Normalized Laplacian Matrix, Seidel Adjacency Matrix, Spectral.
We consider a finite undirected and connected simple graph with vertex set and edge set .We calculated the general formulas of the spectra of a cycle graph and path graph. In this discussion we are interested in the adjacency matrix, Laplacian matrix, signless Laplacian matrix, normalized Laplacian matrix, and seidel adjacency matrix.
