主講人介紹:張曉東教授主要研究圖論與組合及其應(yīng)用,是Theory and Applications of Graphs 、Discrete Mathematics,Algorithms and Applications等雜志編委,中國(guó)運(yùn)籌學(xué)會(huì)圖論組合分會(huì)副理事長(zhǎng),中國(guó)工業(yè)與應(yīng)用數(shù)學(xué)協(xié)會(huì)圖論組合分會(huì)常務(wù)理事。


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.
