题  目： On spectra of signed graphs

报告人：侯耀平   教授 （湖南师范大学数学与统计学院）

摘  要： 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 eigenvalues, and signed graphs with extremal energy.
