An analysis of the 'semi-dissipative' terms in the plasma-dynamical equations

Consideration is given to the terms arising from collision corrections to the pressures and convective energy flows in the equation of state for the total and electrokinetic pressures and the convective part of the total and relative energy flows obtained by applying hydrodynamical projection techniques to a weakly coupled collisionless plasma near equilibrium. It is shown that the unusual semidissipative contributions to the total pressure deviation from equilibrium and to the convective portion of the total and relative energy flows are zero. The semidissipative contributions in the electrokinetic pressure deviation from equilibrium still remain, however, due to the inclusion of terms usually appearing in the friction vector.
