We show that the analytic single-particle density of states and the optical conductivity for the half-filled Hubbard model on the Bethe lattice with infinite connectivity describe quantitatively the behaviour of the gap and the kinetic-energy ratio of the correlated insulator . The form of the optical conductivity shows rising and is quite similar to the experimental data, and the density of states shows behaviour near low-frequency band edges.
