We extend our previous surveys of properties of spectra of signless Laplacians of graphs. Some new theorems for the signless Laplacian eigenvalues are given. In particular, a theorem on spectral characterization of graphs with $Q$-index not exceeding 4 is proved. The signless Laplacian eigenvalues of connected graphs on six vertices are given in Appendix.
Classification : 05C50
