STATISTICAL DESCRIPTION AND TRANSPORT IN STOCHASTIC MAGNETIC-FIELDS

The statistical description of particle motion in a stochastic magneti c field is presented. Starting form the stochastic Liouville equation (or, hybrid kinetic equation) associated with the equations of motion of a test particle, the probability distribution function of the syste m is obtained for various magnetic fields and collisional processes. T he influence of these two ingredients on the statistics of the particl e dynamics is stressed. In all cases, transport properties of the syst em are discussed.
