Abstract
The charge susceptibility and the specific heat of the 1D Hubbard model are calculated by means of the composite operator method for finite temperatur e as functions of filling. A large renormalization of the charge fluctuatio ns appears as the system approaches the metal-insulator transition. (C) 199 9 Elsevier Science B.V. All rights reserved.
