Title: | Signed line graphs with least eigenvalue -2: The star complement technique | Journal: | Discrete Applied Mathematics | Volume: | 207 | First page: | 29 | Last page: | 38 | Issue Date: | 10-Jul-2016 | Rank: | M22 | ISSN: | 0166-218X | DOI: | 10.1016/j.dam.2016.02.018 | Abstract: | We use star complement technique to construct a basis for -2 of signed line graphs using their root signed graphs. In other words, we offer a generalization of the corresponding results known in the literature for (unsigned) graphs in the context of line graphs and generalized line graphs. |
