Extremal trees, unicyclic and bicyclic graphs with respect to $p$ -Sombor spectral radii

Ruiling Zheng, Tianlong Ma, Xian'an Jin

For a graph $G = (V, E)$ and $v_{i} \in V$ , denote by $d_{v_{i}}$ (or $d_{i}$ for short) the degree of vertex $v_{i}$ . The $p$ -Sombor matrix $S_{p} (G)$ ( $p \neq = 0$ ) of…

Two spectral extremal results for graphs with given order and rank

Xiuqing Li, Xian'an Jin, Chao Shi +1

The spectral radius and rank of a graph are defined to be the spectral radius and rank of its adjacency matrix, respectively. It is an important problem in spectral extremal graph…
