On the maximum and minimum multiplicative Zagreb indices of graphs with given number of cut edges

Shaohui Wang, Chunxiang Wang, Lin Chen

For a molecular graph, the first multiplicative Zagreb index $Π_{1}$ is equal to the product of the square of the degree of the vertices, while the second multiplicative Zagreb index…

Total domination polynomials of graphs

Jiuhua Hu, Erfang Shan, Shaohui Wang +2

Given a graph $G$ , a total dominating set $D_{t}$ is a vertex set that every vertex of $G$ is adjacent to some vertices of $D_{t}$ and let $d_{t} (G, i)$ be the number of all total dominat…

Cacti with Extremal PI Index

Chunxiang Wang, Shaohui Wang, Bing Wei

The vertex PI index $P I (G) = \sum_{x y \in E (G)} [n_{x y} (x) + n_{x y} (y)]$ is a distance-based molecular structure descriptor, where $n_{x y} (x)$ denotes the number of vertices which…
