Abstract
Let G = (V, E) be a graph. A set S ⊆ V is a total restrained dominating set if every vertex is adjacent to a vertex in S, and every vertex in V − S is adjacent to a vertex in V −S. The total restrained domination number of G, denoted by γtr (G), is the smallest cardinality of a total restrained dominating set of G. In this paper we show that if G is a graph of order n ≥ 4, then (Formula Presented.). We also characterize the graphs achieving the upper bound.
