The standard three-component extension of the spinless Falicov-Kimball is studied within the dynamical mean-field theory. The extended model consists of an itinerant single component and localized two components. The local Coulomb interaction between model components is also included. The homogeneous phase exhibits the correlation-induced metal-insulator transition. For SU(3) symmetry interaction the metal-insulator transition only occurs at commensurate fillings. For interactions with SU(3)-broken symmetry, the metal-insulator transition additionally occurs at incommensurate half filling.
