Abstract
The relativistic theory of nuclear matter and finite nuclei is reviewed. Both, effective as well as microscopic approaches are discussed. In the latter approach one starts with a one-boson-exchange nucleon-nucleon interaction leading to the Dirac-Brueckner description. In the first method, one formulates the Hartree- (mean field) or Hartree-Fock approximation to some effective Lagrangian which is used to describe directly nuclear matter and finite nuclei. Both approaches are considered and derived in the same framework: the Martin-Schwinger hierarchy of Green's functions. We treat briefly the relativistic Fermi liquid theory, the influence of Δ-degrees of freedom and the situation regarding vacuum fluctuations. We present and discuss results for nuclear matter: saturation properties, equation of state and thermal properties, asymmetric nuclear matter and Landau parameters. In the case of finite nuclei we study optical potentials in nucleon-nucleus scattering and the relation to Dirac phenomenology. Finally, some selected nuclear structure results obtained in Hartree-(Fock) approximation are given.
