A characterization of domination perfect graphs
Igor É. Zverovich, Vadim E. Zverovich · Journal of Graph Theory · 1991
Abstract Let γ(G) and i(G) be the domination number and independent domination number of a graph G, respectively. Sumner and Moore [8] define a graph G to be domination perfect if γ(H) = i(H), for every induced subgraph H of G. In this article, we give a finite forbidden induced subgraph characterization of domination perfect graphs. Bollobás and Cockayne [4] proved an inequality relating γ(G) and i(G) for the class of K1,k ‐free graphs. It is shown that the same inequality holds for a wider class of graphs.
