Abstract

Let $G=(V,E)$ be a graph. A subset $S$ of $V$ is called a dominating set of $G$ if every vertex not in $S$ is adjacent to some vertex in $S.$ The domination number $\gamma(G)$ of $G$ is the minimum cardinality taken over all dominating sets of $G.$ A dominating set $S$ is called a connected dominating set if the subgraph induced by $S$ is connected. The minimum cardinality taken over all connected dominating sets of $G$ is called the connected domination number of $G,$ and is denoted by $\gamma_c(G).$ In this paper, we investigate the Nordhaus-Gaddum type results for the connected domination number and its derived graphs like line graph, subdivision graph, power graph, block graph and total graph, and characterize the extremal graphs.
