To know and be able to apply the Hamiltonian formalism of classical mechanics. 5. To know and be able to apply the methods of the mechanics of a continuous environment within the limits of the relevant courses taught at the Faculty of Physics. 6.

As part of the "Physical Kinetics" course, statistical regularities of the main types of non-equilibrium systems (systems consisting of weakly interacting subsystems, weakly non-equilibrium systems) are considered. The goal of studying the discipline is to acquire systematic knowledge of the basic sections of non-equilibrium statistical physics (general provisions of non-equilibrium statistical physics, the theory of Brownian motion, the theory of linear response) and to master the relevant statistical methods of studying non-equilibrium systems. The educational task of the course consists in mastering the statistical methods of studying non-equilibrium systems
