报告摘要:

Classic Turan-type problem is what is the maximal size of an H-free graph of order n. In 2010, Nikiforov proposed the spectral extremal Turan-type problem: what is the maximum spectral radius of an H-free graph of order n. In 2013, generalized Turan-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 the research progress and our recent work.
