On the Maximum Sigma Index of k-Cyclic Graphs

Akbar Ali, Abeer M. Albalahi, Abdulaziz M. Alanazi +2

Let $G$ be a graph with edge set $E (G)$ . Denote by $d_{w}$ the degree of a vertex $w$ of $G$ . The sigma index of $G$ is defined as $\sum_{uv \in E (G)} (d_{u} - d_{v})^{2}$ . A connected graph o…

On the Vertex-Degree-Function Indices of Connected (n,m)-Graphs of Maximum Degree at Most Four

Abeer M. Albalahi, Igor Z. Milovanovic, Zahid Raza +2

Consider a graph $G$ and a real-valued function $f$ defined on the degree set of $G$ . The sum of the outputs $f (d_{v})$ over all vertices $v \in V (G)$ of $G$ is usually known as the v…
