Title Energy of commuting graph of finite AC- groups Type Article Keywords Commuting graph, non-commuting graph, AC-group, Eigen-value, Energy.10.22199/issn.0717-6279-4365 Abstract LetΓbe a graph with the adjacency matrix A. The energy ofΓis the sum of the absolute values of the eigenvalues of A. In this article we compute the energies of the commuting graphs of some finite groups and discuss some consequences regarding hyperenergetic and border energetic graphs Researchers Reza Sharafdini (First researcher) , Rajat Kanti Nath (Second researcher) , Rezvan Darbandi (Third researcher)
