报告题目：On median eigenvalues of graphs
报 告 人: 杨玉军（烟台大学教授）
报告摘要：Let $G$ be a connected graph of order $n$, and let $\lambda_1\geq \lambda_2 \geq \cdots \geq \lambda_n$ be eigenvalues of the adjacency matrix of $G$. The median eigenvalues of $G$ are $\lambda_H$ and $\lambda_L$, where $H=\lfloor(n+1)/2\rfloor$ and $L= \lceil (n+1)/2\rceil$. In this talk, some recent research progress on median eigenvalues are introduced, with special emphasis being placed on some chemically interesting graphs.
