Han-Kwan, Daniel; Rousset, Frédéric Quasineutral limit for Vlasov-Poisson with Penrose stable data. (Limite quasi neutre pour Vlasov-Poisson avec des données stables au sens de Penrose.) (English. French summary) Zbl 1361.35179 Ann. Sci. Éc. Norm. Supér. (4) 49, No. 6, 1445-1495 (2016). The purpose of this paper is to study a Vlasov-Poisson system for ions in a plasma, where the unknown function is a distribution in the phase space. The main theorem states that this system has a unique solution for stable Penrose initial data. The limit equation for these data is also studied.For the proof appropriate differential operators, which fit together with the Vlasov equation, are introduced. The proofs consist of many steps and use Leibniz and Taylor formulas, Sobolev embedding theorem, Sobolev-Gagliardo-Nirenberg-Moser, Gronvall, Cauchy-Schwartz, Bessel inequalities, Fourier transform.
