Abstract:
The concept of graph energy is a frontier between two important branches of basic sciences:
namely, Mathematics and Chemistry. The sum of absolute values of eigenvalues of adjacency matrix of graph is called the energy of a graph. The graph energy of some standard graphs is available in literature while we have investigated the energy of a graphs which are obtained from the duplication of graph elements (Vertex and Edge) in a given graph. Keywords: Duplication, Eigenvalue, Energy of Graphs
