WebAug 4, 2010 · In Section 4.2 we establish a spectral characterization of regular line graphs: we use the methods of [CvDo2], and a reformulation of results from [BuCS1] and [BuCS2], to provide a computer-free proof. Some characterizations of special classes of line graphs are given in Section 4.3.

"Web160 CHAPTER 4. SIGNED GRAPHS Such graphs (with weights (1,0,+1)) were introduced as early as 1953 by Harary [9], to model social relations involving disliking, indi↵erence, and liking. The problem of clustering the nodes of a signed graph arises naturally as a generalization of the clustering prob-lem for weighted graphs. " - Spectral generalizations of line graphs
