In this note we address the problem of graph isomorphism by means of eigen-value spectra of different matrix representations: the neighborhood matrixˆM , its corresponding signless Laplacian Q ˆ M , and the set of higher order adjacency matrices M s. We find that, in relation to graphs with at most 10 vertices, Q ˆ M leads to better results than the(More)
