N2 - We examined the characteristics of a metal-insulator transition on a two-dimensional nonbipartite lattice when both disorders and electron interactions are present. Using a real-space renormalization group method and finite-size scaling analysis we have found that after the disordered system transits from the insulating state to the metal one, it can reenter an insulating state if there is a further increase in the electron-electron interactions.
