On the basis of a quantum-statistical formulation of electronic transport in charged-particle systems, the electrical conductivity of a high-density fully ionized plasma is evaluated using a diagram representation of the Matsubara Green functions. Many-particle effects such as the Debye-Onsager relaxation effect are investigated, and a low-density expansion of the inverse conductivity ${\mathrm{\sigma }}^{\mathrm{-}1}$(T,n)=A(T)lnn+B(T)+C(T)${\mathrm{n}}^{1/2}$lnn+⋅⋅⋅ as a function of temperature T and density n is obtained. Approximative expressions are given for the functions A(T), B(T), and C(T) in the quasiclassical limit, and the resulting conductivity is compared with experiments.
