The signless Laplacian spectral radius of graphs without trees

Ming-Zhu Chen, Zhao-Ming Li, Xiao-Dong Zhang

Let $Q (G) = D (G) + A (G)$ be the signless Laplacian matrix of a simple graph of order $n$ , where $D (G)$ and $A (G)$ are the degree diagonal matrix and the adjacency matrix of $G$ , respec…

Spectral extremal results on the $α$ -index of graphs without minors and star forests

Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang

Let $G$ be a graph of order $n$ , and let $A (G)$ and $D (G)$ be the adjacency matrix and the degree matrix of $G$ respectively. Define the convex linear combinations $A_{α} (G)$ of $A (…

The bipartite Turan number and spectral extremum for linear forests

Ming-Zhu Chen, Ning Wang, Long-Tu Yuan +1

The bipartite Turán number of a graph $H$ , denoted by $e x (m, n; H)$ , is the maximum number of edges in any bipartite graph $G = (X, Y; E)$ with $∣ X ∣ = m$ and $∣ Y ∣ = n$ which does not conta…
