Abstract
A dominating set D of G is a subset of V(G), such that every vertex in \(V(G){\setminus } D\) is adjacent to at least one vertex in D. A neighborhood total dominating set, abbreviated for NTD set D, is a dominating set of G with an extra property: the subgraph induced by the open neighborhood of D, denoted by G[N(D)], has no isolated vertices. The neighborhood total domination number, denoted by \(\gamma _{nt}(G)\), is the minimum cardinality of an NTD set in G. A classical result of Vizing relates the size and the domination number of a graph of given order. In this paper, we present a Vizing-like result for \(\gamma _{nt}(G)\). Some results for \(\gamma _{nt}(G)\) in terms of other graphic parameters, such as girth, diameter, and degree of G, are also obtained.
