A note on the independent domination number versus the domination number in bipartite graphs

Shaohui Wang, Bing Wei

Let $γ (G)$ and $i (G)$ be the domination number and the independent domination number of $G$ , respectively. Rad and Volkmann posted a conjecture that $i (G) / γ (G) \leq Δ (G) /2$ for an…

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…

Multiplicative Zagreb indices of k-trees

Shaohui Wang, Bing Wei

Let G be a graph with vertex set V (G) and edge set E(G). The first generalized multiplicative Zagreb index of G is M_1(G) and the second multiplicative Zagreb index is M_2(G). The…
