摘要

连通图$G$的代数连通性是$G$的拉普拉斯矩阵的第二小特征值。本文通过对一个适当的商矩阵进行广义交错,得到了代数连通性的一些新的上界。

Upper bounds on the algebraic connectivity of graphs
The algebraic connectivity of a connected graph $G$ is the second smallest eigenvalue of the Laplacian matrix of $G$. In this paper, some new upper bounds on algebraic connectivity are obtained by applying generalized interlacing to an appropriate quotient matrix.
