Signed analogue of line graphs and their smallest eigenvalues

Alexander L. Gavrilyuk, Akihiro Munemasa, Yoshio Sano +1

In this paper, we show that every connected signed graph with smallest eigenvalue strictly greater than $- 2$ and large enough minimum degree is switching equivalent to a complete g…
