Реферат: eng: This paper is devoted to applications of the group analysis method to the Boltzmann equation with a source function. Exact solutions of the nonlinear kinetic Boltzmann equation with a source function in the case of an isotropic distribution function and Maxwell model of isotropic scattering were constructed. An equivalence Lie group is used for the construction. One of the transformations of the equivalence Lie group uniquely singles out a class of source functions which allows us to find invariant solutions of the Bobylev-Krook-Wu type in an explicit form. In particular, some of these solutions have a meaningful physical interpretation.
