Leila Parsaei Majd (Shahid Rajaee University, Teheran):
Spectra of signed graphs

Abstract:
Let G be a signed complete or complete bipartite graph. We state some properties of the spectrum of the adjacency matrix of G. Also, if the negative edges of G form a matching, we determine the spectrum exactly.

Moreover, we give two types of constructions of signed complete graphs whose spectra are symmetric.
