Abstract
We present a solution of the Hubbard model at half filling in the limit of infinite dimensions which corresponds to the Mott-Hubbard insulating phase. We describe the metal-insulator transition between this regime and the Fermi-liquid regime. Our analysis is based on an analytic consideration and exact Monte Carlo simulations at low but finite temperatures.
