Abstract
Recurrence procedure for constructing kernels of the integral operators arising in expansion of the nonlinear Boltzmann collision integral in Legendre polynomials is realised in “Mathematica” system for the hard spheres gas. All the kernels with increasing indices corresponding to the Legendre polynomials indices are subsequently calculated up to sum of indices equal to 40. The main features of the kernels as functions of their indices are considered. The kernels can be used to solve the nonlinear Boltzmann equation in strongly anisotropic case.
