A set $$S$$ S of vertices in graph $$G$$ G is a total dominating set of $$G$$ G if every vertex of $$G$$ G is adjacent to some vertex in $$S$$ S . The minimum cardinality of a total dominating set of $$G$$ G is the total domination number $$\gamma _t(G)$$ γ t ( G ) . A graph $$G$$ G with no isolated vertex is total domination...
Let G be a graph of order n and maximum degree Δ(G) and let γt(G) denote the minimum cardinality of a total dominating set of a graph G. A graph G with no isolated vertex is the total domination vertex critical if for any vertex v of G that is not adjacent to a vertex of degree one, the total domination number of G−v is less than the total domination number of G. We call these graphs γt-critical....
