Spectral bounds for the independence number of graphs and even uniform hypergraphs

Xinyu Hu, Jiang Zhou, Changjiang Bu

In this paper, we give spectral upper bounds for the independence number of even uniform hypergraphs and graphs, extend the Hoffman bound to even uniform hypergraphs, and give a si…

Quadratic form estimations for Hessian matrices of resistance distance and Kirchhoff index of positive-weighted graphs

Yu Li, Lizhu Sun, Changjiang Bu

Let $G^{w} = (V, E, w)$ be a positive-weighted graph with the weight $w (e) > 0$ for all $e \in E$ . The weighted graph $G^{w} = (V, E, w)$ is called a hyper-dual number…
