A graph is k-connected if it has k pairwise internally node disjoint paths between every pair of its nodes. A subset S of nodes in a graph G is a k-connected set if the subgraph G[S] induced by S is k-connected; S is an m-dominating set if every v∈V∖S has at least m neighbors in S. If S is both k-connected and m-dominating then S is a k-c...More
