Title: On spectra of signed graphs
Abstract: In this talk, we I will introduce some recent results on eigenvalues of signed graphs, such as signed graphs with few disitinct eigenvalues, integral subcubic signed graphs, the muliplicity of eigenvalues, and the signed graphs with spectral radius does not exceed $\sqrt{2+\sqrt{5}}.$
