    The signed and minus \(k\)-subdomination numbers of certain complete multipartite graphs and their complements (English)
    0 references
    The signed (minus) \(k\)-subdomination number of a graph \(G=(V,E)\) is the minimum weight \(f(V)=\sum_{u\in V}f(u)\) of a function \(f:V\to \{ -1,1\}\) (\(f:V\to \{ -1,0,1\}\)) such that \(f(N[u])\geq 1\) for at least \(k\) vertices \(u\in V\). The authors determine these two domination parameters for complete graphs, complete bipartite graphs, disjoint unions of two complete graphs and split graphs.
