摘要：

In this study, we calculate the dc resistivity of the half-filled disordered Hubbard model near the Mott and Anderson metal-insulator transitions. We employ the standard Kubo formula with typical medium dynamical mean field theory to perform our calculations. Our investigation explores the effects of random potential, on-site Coulomb interaction, and temperature on the dc resistivity within the model. In addition, we highlight and discuss the distinct resistivity behaviors observed near the Mott and Anderson transitions.
