Реферат: eng: This article is devoted to group analysis of the spatially homogeneous and isotropic Boltzmann equation with a source term. In fact, the Fourier transform of the Boltzmann equation with respect to the molecular velocity variable is considered. Complete group classification with respect to a source function only depending on the independent variables is performed. If a source term includes the dependent variable, then preliminary group classification is given. In the case where the source function also depends on a nonlocal term (number of particles), extension of the equivalence Lie group occurs. Using these equivalence transformations and preliminary group classification, reduced equations are derived, and their generalized BKW-solutions are obtained in an explicit form. © 2019 Author(s).
