摘      要：

         Spectral extremal problem was firstly proposed by Brualdi and Solheid in 1986. In 2010, a variation of spectral extremal problem and Tur'{a}n-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 Tur'{a}n-type problem. Nice results were consecutively presented and spectral extremal techniques were greatly developed. In this talk, we introduce a variation of spectral Tur'{a}n-type problem, that is, what is the maximum spectral radius of an H-free graph on m edges?
