报告内容介绍

In this talk, a close relation between the normalized Laplacians and the hitting time of random walks on a graph is displayed. Combining graph transformations and some other techniques, sharp upper and lower bounds on the cover cost (resp. reverse cover cost), the multiplicative degree-Kirchhoff index, the number of spanning trees of graphs are determined. All the corresponding extremal graphs are identified.
