报告摘要:Spectral extremal problem was firstly proposed by Brualdi and Solheid in 1986.In 2010, a variation of spectral extremal problem and Turan-type problem was given by Nikiforov, who asked what is the maximum spectral radius of an H-free graph of order n? In the past decades, much attention has been paid to this spectral Turan-type problem. Nice results were consecutively presented and spectral extremal techniques were greatly developed. Meanwhile, some conjectures and open questions were proposed. In this talk, we give a brief survey on current progress of these conjectures and open questions. If possible, we also introduce some corresponding techniques.
