Interest in kinetic equations is associated with the possibility of their application in various fields of mechanics and physics - in the kinetic theory of gas, suspended particle mechanics, plasma, astrophysics, reactor theory. The book is written as an elevated type textbook. It gives a clear statement of the foundations of the theory of kinetic equations, discusses methods for analyzing the Boltzmann equation, considers questions about approaching an equilibrium state, about the ratio between micro- and macro-states.
