主 题:The Normalized Laplacian Eigenvalues of Graphs
内容简介:The normalized Laplacian matrix of a graph was introduced by F. Chung in 1997. Its eigenvalues are closely related to almost all major invariants (such as diameter, clique number, Cheegers invariant, \emph{etc}) of a graph, linking one extremal property to another. There is no question that normalized Laplacian eigenvalues play a central role in our fundamental understanding of graphs. In this talk, we focus on the study of the relationships between the normalized Laplacian eigenvalues of a graph and its structural properties, some results on normalized Laplacian eigenvalues of a graph, including its normalized Laplacian characteristic polynomial, normalized Laplacian spectral radius and normalized algebraic connectivity, are presented. This talk is based on the joint work with An Chang, Ji-Ming Guo and Wai Chee Shiu.
