Asymptotic behaviour of the Boltzmann equation as a cosmological model
Asymptotic behaviour of the Boltzmann equation as a cosmological model
As a Newtonian cosmological model the Vlasov-Poisson-Boltzmann system is considered, and a slightly modified Boltzmann equation, which describes the stability of an expanding universe, is derived. Asymptotic behaviour of solutions turns out to depend on the expansion of the universe, and in this paper we consider the soft potential case …
