ENERGY OF MONAD GRAPHS.

Let G be a digraph of order n. The energy of G is the sum of absolute values of the real parts of the eigenvalues of its adjacency matrix. The monad graph is a digraph pertaining to the finite group G, where every vertex of the elements g of G is adjacent to its image by a directed edge under the action of the map f(g) = g². In this paper, we compute the energy of monad graphs. [ABSTRACT FROM AUTHOR]
