On the Extremal Zagreb Indices of $n$ -Vertex Chemical Trees with Fixed Number of Segments or Branching Vertices

Sadia Noureen, Akbar Ali, Akhlaq Ahmad Bhatti

Let $C T_{n, k}$ and $C T_{n, b}^{*}$ be the classes of all $n$ -vertex chemical trees with $k$ segments and $b$ branching vertices, respectively, where $3\le k\le n-1…

A Note on the Modified Albertson Index

Shumaila Yousaf, Akhlaq Ahmad Bhatti, Akbar Ali

The modified Albertson index, denoted by $A^{*}$ , of a graph $G$ is defined as $A^{*} (G) = \sum_{uv \in E (G)} ∣ (d_{u})^{2} - (d_{v})^{2} ∣$ , where $d_{u}$ , $d_{v}$ denote the degrees of…
