Название: Discretized Boltzmann equation: Lattice limit and non-Maxwellian gases
Авторы: William Greenberg, Jürgen Voigt, P. F. Zweifel
We continue the study of a discrete model of the Boltzmann equation, in which the spatial variable is replaced by a finite periodic lattice. Using a weak compactness criterion forL 1, the existence of a lattice limit as the lattice spacing tends to zero is proved. The case of unbounded collision kernels (non-Maxwellian gases) is also treated.
