Abstract
A comparison of two methods in the relativistic kinetic theory of the Fermi systems is carried out by assuming, as an example, the simplest sigma omega-version of quantum hadrodynamics with allowance for strong mean meson fields. It is shown that the Vlasov-type relativistic kine tic equation (VRKE) obtained by means of the procedure of squaring at an intermediate step is responsible for unphysical features. A direct method of derivation of kinetic equations is proposed. This method doe s not contain such drawback and gives rise to VRKE in hadrodynamics of a non-contradictory form in which both spin degrees of freedom and st ates with positive and negative energies are taken into account.
