Reza Sharafdini, Rajat Kanti Nath, Rezvan Darbandi

• Let Γ be a graph with the adjacency matrix A. The energy of Γ is 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 borderenergetic graphs.
