报告题目：Spectral Dynamics of Graph Eigenvalues
报告摘要：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.
