Abstract

In the present paper we give approximative expressions of the generalized density matrix of Bloch, which can be calculated exactly for the case of free electrons in a uniform magnetic field, while for the case of lattice electrons it can be expressed by the help of the Wannier functions. For the case of high temperatures the generalized density matrix coincides to the Green-function.
