报告摘要:In this talk I will present a newly proposed random graph model, which yields a larger proportion of connected graphs. I will discuss the eigenvalue problem for the discrete Laplacian on this model and derive both upper and lower bounds for the first (nonzero) eigenvalue. The talk will present the model construction, main proof ideas, and an application of the eigenvalue estimates in geometry. This is a joint work with Bobo Hua and Yang Shen.
