Аннотация:
In this paper, we consider the discrete kinetic Carleman system.
The Carleman system is the Boltzmann kinetic equation, and for this model
momentum and energy are not conserved. Using group analysis methods, we
obtain a solution representing the density of gas particles in a certain area. This
limitation is due to the non-negativity of solution. Similarly, it is possible to
find exact solutions for other kinetic models.
