A method is established for the approximate calcuiation of the density matrix for a system of interacting anharmonic osciUators. An approximate analytical expression is obtained for the density matrix of a two-dimensional isotropic %nharmonk osciIIator. As an example the calculations for a two-dimen
It is shown that the local thermodynamic description of the ground state of a many-electron system, earlier proposed by Ghosh, Berkowitz and Parr, is equivalent to a well defined approximation for the density matrix and therefore for the Wigner's distribution.
