摘要:Classic Tur'{a}n-type problem is what is the maximal size of an H-free graph of order n? In 2010, Nikiforov proposed the spectral extremal Tur'{a}n-type problem: what is the maximum spectral radius of an H-free graph of order n? In 2013, generalized Tur'{a}n-type problem was proposed and the question what is the maximum spectral radius of an H-free graph on m edges was studied. In this talk, we introduce theresearch progress and our recent work.
