SPECTRAL CHARACTERIZATIONS OF LINE GRAPHS. VARIATIONS ON THE THEMEDrago\v s M. Cvetkovi\'cElektrotehnicki fakultet, Beograd, YugoslaviaAbstract: The following three topics related to spectral characterizations of line graphs are discussed: local structure of regular graphs with the least eigenvalue $-2$ which contain $K_{1,3}$ as an induced subgraph, switching regular line graphs into regular graphs which are not line graphs, and line switching (of graphs) as a modification of familiar (vertex) switching.
