The explicit expressions are found for the effective potentials and the unscreened part of the grain charge. The friction force acting on the finite-size grain is calculated and the conditions for the negative friction are established. The effective potential of charged macroparticle is studied at the arbitrary value of coupling between plasma particles and grain. The dependence of the effective particle charge on its size and plasma parameters is described. The action of the fluctuation force acting on the charged particle is calculated taking into account the presence of external magnetic field. The correction to the Holtsmark formula due to the magnetic field is obtained. A new approach to the electric fluctuation description in dusty plasma is proposed for the wide range of the plasma particle-neutral collision frequency. The theory of collective diffusion of colloidal particles in liquid crystals is worked out. Product Description popup.authors А.І. Момот Б.І.Лев В.Б. Тимчишин Г.С. Драган Засенко В.І. О.М.
