The kinetic approach developed in the present discussion of the role of relativistic effects in the problem of inhomogeneous magnetized plasma drift instabilities takes into account a nonzero plasmapressure and the EM character of the perturbations. The general dispersion relation for the perturbations in an inhomogeneous relativistic plasma is obtained and expressed in terms of the modified dielectric permittivity tensor, which is calculated by taking into account the non-Maxwellian character of the particles' equilibrium momentum distributions. In the second part of this work, the generalization of the theory is given for the case of a relativistic plasma, and the role of relativistic effects is clarified by taking the anisotropy of the particle momentum distribution function into account. Attention is given to instabilities of these perturbations in a relativistic electron-positron plasma.
