abstract

  • AbstractLet G be a graph of minimum degree at least 2 with no induced subgraph isomorphic to K1, 6. We prove that if G is not isomorphic to one of eight exceptional graphs, then it is possible to assign twoelement subsets of to the vertices of G in such a way that for every and every vertex the label i is assigned to v or one of its neighbors. It follows that G has fractional domatic number at least 5/2. This is motivated by a problem in robotics and generalizes a result of Fujita, Yamashita, and Kameda who proved that the same conclusion holds for all 3regular graphs.
