WebFor the Petersen graph, for example, the spectrum of the adjacency matrix is (−2, −2, −2, −2, 1, 1, 1, 1, 1, 3). Several theorems relate properties of the spectrum to other graph properties. As a simple example, a connected graph with diameter D will have at least D+1 distinct values in its spectrum. Aspects of graph spectra have been ...

WebAdjacency matrix representation makes use of a matrix (table) where the first row and first column of the matrix denote the nodes (vertices) of the graph. The rest of the cells contains either 0 or 1 (can contain an associated weight w if it is a weighted graph). Each row X column intersection points to a cell and the value of that cell will ...
