## Split Domination, Independence, and Irredundance in Graphs

16 May 2016  ·  Hedetniemi Stephen, Knoll Fiona, Laskar Renu ·

In 1978, Kulli and Janakiram \citep{KulliJanakiramSplit} defined the split dominating set: a dominating set $S$ of vertices in a graph $G = (V, E)$ is called {\em split dominating} if the induced subgraph $\langle V \setminus S\rangle$ is either disconnected or a $K_1$. In this paper we introduce the properties split independence and split irredundance... A set $S$ of vertices in a graph $G =(V,E)$ is called a {\em split independent set} if $S$ is independent and the induced subgraph $\langle V \setminus S \rangle$ is either disconnected or a $K_1$. A set $S$ of vertices in a graph $G = (V,E)$ is called a {\em split irredundant set} if for $u \in S$, $u$ has a private neighbor with respect to $V(S)$ and the induced subgraph $\langle V \setminus S\rangle$ is either disconnected or a $K_1$. read more
