Title: | Signed Graphs with totally disconnected Star Complements | Authors: | Stanić, Zoran | Affiliations: | Numerical Mathematics and Optimization | Keywords: | adjacency matrix;exceptional signed graph;Signed graph decomposition;signed line graph;star set | Issue Date: | 1-Jan-2021 | Rank: | M23 | Publisher: | Unión Matemática Argentina | Journal: | Revista de la Union Matematica Argentina | Abstract: | We are interested in a signed graph Ġ which admits a decomposition into a totally disconnected (i.e., without edges) star complement and a signed graph Ṡ induced by the star set. In this study we derive certain properties of Ġ; for example, we prove that the number of (distinct) eigenvalues of Ṡ does not exceed the number of those of Ġ. Some particular cases are also considered. |
