Decompositions of graphs with degree constraints relative to prescribed subgraphs

Peichao Wei, Muhuo Liu, Yang Wu +1

Given a finite simple undirected graph $G$ , let $T_{1} (G)$ denote the subset of vertices of $G$ such that every vertex of $T_{1} (G)$ belongs to at least one subgraph isomorphic to a gr…

Note on Sombor index of connected graphs with given degree sequence

Peichao Wei, Muhuo Liu

For a simple connected graph $G = (V, E)$ , let $d (u)$ be the degree of the vertex $u$ of $G$ . The general Sombor index of $G$ is defined as $$SO_α(G)=\sum_{uv\in E} \left[d(u)^2+d(v)^…
