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 -graphs, the graphs with the minimum algebraic connectivity are completely determined, respectively.
Least -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 -graphs, the minimum least -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 -uniform () unicyclic hypergraphs with matching number at least , 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 among the connected nonbipartite graphs on vertices and with domination number $\frac{n+1}{3}<γ\leq \frac{n…
Maxima of the -index for outer-planar graphs
Guanglong Yu
The - of graph is the largest eigenvalue of its signless Laplacian . In this paper, we prove that the graph has the maximal -ind…
