On a Conjecture About the Sombor Index of Graphs

Kinkar Chandra Das, Ali Ghalavand, Ali Reza Ashrafi

Let $G$ be a graph with vertex set $V (G)$ and edge set $E (G)$ . The Sombor and reduced Sombor indices of $G$ are defined as $S O (G) = \sum_{uv \in E (G)} d e g_{G} (u)^{2} + d e g_{G} (v)^{2}$ and…

On the Relation Between Wiener Index and Eccentricity of a Graph

Hamid Darabi, Yaser Alizadeh, Sandi Klavžar +1

The relation between the Wiener index $W (G)$ and the eccentricity $ε (G)$ of a graph $G$ is studied. Lower and upper bounds on $W (G)$ in terms of $ε (G)$ are prov…
