摘要
A set D of vertices in a graph G - (V, E) is said to be a total dominating set of G if every vertex in V is adjacent to some vertex in D. The total domination number gamma(t)(G) is the minimum cardinality of a total dominating set. E(G(-)) denotes the edge set of G(-), the complement of G. The minimum cardinality of a set E-1 subset of E(G(-)) for which gamma(t)(G+ E1) < gamma(t)(G) is denoted by r(t)(G) and is called the total reinforcement number of G. The number r(t)(G) is well defined if gamma(t)(G) > 2. In this paper, we obtain some results on the total reinforcement number of a graph.
