Extremal trees with respect to spectral radius of restrictedly weighted adjacency matrices

Ruiling Zheng, Xiaxia Guan, Xian an Jin

For a graph $G = (V, E)$ and $v_{i} \in V$ , denote by $d_{i}$ the degree of vertex $v_{i}$ . Let $f (x, y) > 0$ be a real symmetric function in $x$ and $y$ . The weighted adjacency matrix $…

Arithmetic-Geometric spectral radii of Unicyclic graphs

Ruiling Zheng, Xian'an Jin

Let $d_{v_{i}}$ be the degree of the vertex $v_{i}$ of $G$ . The arithmetic-geometric matrix $A_{a g} (G)$ of a graph $G$ is a square matrix, where the $(i, j)$ -entry is equal to $\dis…

Arithmetic-Geometric Spectral Radius of Trees and Unicyclic Graphs

Ruiling Zheng, Xian, an Jin

The arithmetic-geometric matrix $A_{a g} (G)$ of a graph $G$ is a square matrix, where the $(i, j)$ -entry is equal to $\frac{d _{i} + d _{j}}{2 d _{i} d _{j}}$ if the ver…
