內(nèi)容介紹:The Turan problems ask to maximize the number of edges over all graphs which do not contain a copy of F. Similarly, spectral Turan problems ask to maximize the spectral radius of all graphs which do not contain a copy of F. In this talk, we report the recent progress on spectral Turan problems.
