Minimum Atom-Bond Sum-Connectivity Index of Trees With a Fixed Order and/or Number of Pendent Vertices

Tariq A. Alraqad, Igor Z. Milovanovic, Hicham Saber +3

Let $d_{u}$ be the degree of a vertex $u$ of a graph $G$ . The atom-bond sum-connectivity (ABS) index of a graph $G$ is the sum of the numbers $(1 - 2 (d_{v} + d_{w})^{- 1})^{1/2}$ over all edg…

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…

The $k$ -apex trees with minimum augmented Zagreb index

Muhuo Liu, Shumei Pang, Francesco Belardo +1

For a connected graph $G$ on at least three vertices, the augmented Zagreb index (AZI) of $G$ is defined as $$AZI(G)=\sum_{uv\in E(G)}\left(\frac{d(u)d(v)}{d(u)+d(v)-2}\right)^{3},…
