Generalized power domination in claw-free regular graphs

Hangdi Chen, Changhong Lu, Qingjie Ye

In this paper, we give a series of couterexamples to negate a conjecture and hence answer an open question on the $k$ -power domination of regular graphs (see [P. Dorbec et al., SIA…

A Note on Roman \{2\}-domination problem in graphs

Hangdi Chen, Changhong Lu

For a graph $G = (V, E)$ , a Roman ${2}$ -dominating function (R2DF) $f : V \to {0, 1, 2}$ has the property that for every vertex $v \in V$ with $f (v) = 0$ , either there exists a nei…
