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…

The domination number and the least Q-eigenvalue II

Guanglong Yu

Denote by $L_{g, l}$ the $l o l l i p o p$ $g r a p h$ obtained by attaching a pendant path $P = v_{g} v_{g + 1} \dots v_{g + l}$ ( $l \geq 1$ ) to a cycle $\mathbb{C}=v_{1}v_{2}\cdots v_{g}v_…
