Abstract
The quasifermion approximation based on the weakening of conditions im posed on the density matrix of a many-electron system is considered in the present paper. In this approximation, a rather simple constructio n for the density matrix and for the energy can be obtained. The appli cation of this approximation to a variety of materials science problem s is shown to be in good agreement with experimental results.
