报告摘要:ClassicTur'{a}n-type problemis what is the maximal size of an H-free graph of order n?In 2010, Nikiforovproposed thespectral extremal Tur'{a}n-type problem:what is the maximum spectral radius of an H-free graph of order n?In 2013, generalizedTur'{a}n-type problemwas proposed and the questionwhat is the maximum spectral radius of an H-free graphon m edgeswas studied. In this talk, we introduce theresearch progress and our recent work.
