應(yīng)張和平教授邀請,廈門大學(xué)張?;淌趯⒂?023年6月28 日下午作學(xué)術(shù)報(bào)告。
報(bào)告題目:Spectral Dynamics of Graph Eigenvalues
報(bào)告時(shí)間:6月28日下午16:30
報(bào)告地點(diǎn):城關(guān)校區(qū)理工樓 401報(bào)告廳
報(bào)告摘要:In this talk I will survey results related to spectral dynamics of graph eigenvalues, mainly about the distribution of k-th largest eigenvalues of graphs, the distribution of bipartite regular graphs and bipartite regular digraphs and spectral dynamics of iterations of clique inserting and present the sketch of proofs of several main theorems. Many open problems are provided. Then I will discuss the normalized Laplacian spectral dynamics produced by iterations of other unary graph operations. We will show that in the procedure of iterated subdivision, chaos happen in the limits of normalized Laplacian eigenvalues of iterated subdivision of a graph G.
歡迎廣大師生參加!
