Mullai Laboratory of Information processing, Faculty of Sciences , Ben M’SiK, University Hassan II,B.P 7955, Sidi Othman, Casablanca, Morocco Said Broumi Dominating energy of graphs plays a vital role in the field of application in energy. Results by applying neutrosophic graph theory is more efficient than other existing methods. So, dominating energy of neutrosophic graphs will also give more accurate results than other exixting methods in the field of energy. This article introduces dominating energy of neutrosophic graphs. Dominating energy of a neutrosophic graph, dominating neutrosophic adjacency matrix, eigen values for the dominating energy of a neutrosophic graphs and complement of neutrosophic graphs are defined with examples. Also, dominating energy in union and join operations of neutrosophic graphs are developed and some theorems in dominating energy of a neutrosophic graphs are derived here. 2020 2020 38 58 10.54216/IJNS.050104 https://www.americaspg.com/articleinfo/21/show/377
