Independent Double Roman Domination on Block Graphs

Decheng Wei, Changhong Lu

Given a graph $G = (V, E)$ , $f : V \to {0, 1, 2}$ is the Italian dominating function of $G$ if $f$ satisfies $\sum_{u \in N (v)} f (u) \geq 2$ when $f (v) = 0$ . Denote $w(f)=\sum_{v…

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…
