Let D be a simple digraph without loops or digons. For any v ∈ V (D), the first out-neighborhood N(v) is the set of all vertices with out-distance 1 from v and the second neighborhood N(v) of v is the set of all vertices with out-distance 2 from v. We show that every simple digraph without loops or digons contains a vertex v such that |N++(v)| ≥ γ|N+(v)|, where γ = 0.657298 . . . is the unique ...
