Topic: On spectra of signed graphs

Speaker: Hou Yaoping

Abstract: A signed graph consists of an unsigned graph and a sign function. In this talk, we will introduce some results on the spectra of signed graphs, such as analogue to Brouwer's conjecture, signed graphs with exactly two distinct eigenvaules, and signed graphs with extremal energy.
