An “equation‐of‐motion method” is used for calculating the one‐particle density matrix. In this way an exact electron transport equation is derived in terms of the Green function of the Liouville equation. Approximations are developed which are applicable to simple liquid metals when the “mean free path” is comparable with the atomic spacing.
