With the help of the Kubo formula an expression for the transverse electrical conductivity of metals is obtained within the Hartree‐Fock approximation using the method of the double‐time temperature‐dependent Green's function. It is observed that the expression is the same as that obtained by Leribaux with the help of perturbation theory using the Feynman diagram technique if the change in the energy of the electrons due to electron‐phonon interaction is neglected.
