Abstract
The theoretical aspects of cosmic ray transport in the Galaxy are discussed. The emphasis is on the diffusion model of cosmic ray propagation. The results of the empirical modelling are combined with the approach based on the kinetic theory of particle interaction with random magnetic fields. The plasma effects of cosmic rays in the interstellar medium are briefly discussed.
► Diffusion model provides good description of cosmic ray propagation in the Galaxy. ► Uncertainty remains in the dependence of cosmic ray diffusion on magnetic rigidity. ► Supernova remnants can provide cosmic ray acceleration up to about 10∗∗8 GV. ► New deviations from the plain power laws were observed in cosmic ray spectra.
