On the sum of the largest $A_{α}$ -eigenvalues of graphs

Zhen Lin, Lianying Miao, Shuguang Guo

For every real $0 \leq α \leq 1$ , Nikiforov defined the $A_{α}$ -matrix of a graph $G$ as $A_{α} (G) = α D (G) + (1 - α) A (G)$ , where $A (G)$ and $D (G)$ are the adjacency matrix and the degree diago…

On the Ky Fan $k$ -norm of the $L I$ -matrix of graphs

Zhen Lin, Lianying Miao, Guanglong Yu +1

Let $A (G)$ and $D (G)$ be the adjacency matrix and the degree diagonal matrix of a graph $G$ , respectively. Then $L (G) = D (G) - A (G)$ is called Laplacian matrix of the graph $G$ . Let $G…
