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 ${\text{S}}_{\text{p}}(G)$ ($p\ne 0$) of…
