Affiliations: | Numerical Mathematics and Optimization | Keywords: | adjacency matrix;association scheme;simple eigenvalue;strongly regular signed graph;vertex-deleted subgraph;weighing matrix | Issue Date: | 2022 | Rank: | M22 | Publisher: | Zielona Gora : University of Zielona Gora, Institute of Mathematics | Journal: | Discussiones Mathematicae - Graph Theory | Abstract: | We consider signed graphs with just 2 or 3 distinct eigenvalues, in particular (i) those with at least one simple eigenvalue, and (ii) those with vertex-deleted subgraphs which themselves have at most 3 distinct eigenvalues. We also construct new examples using weighing matrices and symmetric 3-class association schemes. |
