A note on algebraic connectivity of 2-connected graphs

Guanglong Yu, by Shuguang Guo, Lin Sun +2

Among all simple 2-connected graphs, and among all $θ$ -graphs, the graphs with the minimum algebraic connectivity are completely determined, respectively.

Least $Q$ -eigenvalues of nonbipartite 2-connected graphs

Guanglong Yu, by Lin Sun, Chao Yan +2

Among all simple nonbipartite 2-connected graphs and among all nonbipartite $θ$ -graphs, the minimum least $Q$ -eigenvalues are completely determined, respectively.

On the spectral radii of the unicyclic hypergraphs with fixed matching number

Guanglong Yu, Chao Yan, Yarong Wu +1

We determine the unique hypergraphs with maximum spectral radius among all connected $k$ -uniform ( $k \geq 3$ ) unicyclic hypergraphs with matching number at least $z$ , and among all…

Further results on the least Q-eigenvalue of a graph with fixed domination number

Guanglong Yu, Yarong Wu, Mingqing Zhai

In this paper, we proceed on determining the minimum $q_{min}$ among the connected nonbipartite graphs on $n \geq 5$ vertices and with domination number $\frac{n+1}{3}<γ\leq \frac{n…
