Cvetković, D.
Signless Laplacians and line graphs. (English)
[J] Bull., Cl. Sci. Math. Nat., Sci. Math. 131, No. 30, 85-92 (2005). ISSN 0561-7332

The spectrum of a graph is the spectrum of its adjacency matrix. The author studies the phenomenon of cospectrality in graphs by comparing characterizing properties of spectra of graphs and spectra of their line graphs. In this comparison spectra of signless Laplacians of graphs are used.
