Odd Vertex Out-Magic Total Labeling of Some 2-Regular Digraphs

Abstract

Let D(V, A) be a directed graph of order p and size q. An Odd vertex out-magic total labeling (OVOMTL) of a graph D is bijection f : V(D) ∪ A(D) → {1, 2, … p + q} in order f (V(D)) = {1, 3, …, 2p − 1}, for all υ ∈ V (D), , a constant. A uGo(v) digraph which admits an OVOMTL is termed as Odd Vertex out-magic total (OVOMT). Herein, we emphasize on feature of some 2-regular directed graphs that are Odd Vertex out-magic total (OVOMT).
