The upper domatic number of a graph
Let be a graph. For two disjoint sets of vertices and , set dominates set if every vertex in is adjacent to at least one vertex in . In this paper we introduce the upper domatic number , which equals the maximum order of a vertex partition such that for every , , either dominates or dominates , or b...
