The Vlasov-Poisson-Boltzmann/Landau system with polynomial perturbation near Maxwellian
Résumé
In this work, we consider the Vlasov-Poisson-Boltzmann system without angular cutoff and the Vlasov-Poisson-Landau system with Coulomb potential near a global Maxwellian µ. We establish the global existence, uniqueness and large time behavior for solutions in a polynomial-weighted Sobolev space$H^2_{x,v} (\langle v\rangle^ k)$ for some constant k > 0. For the domain union of cubes, We will consider the specular-reflection boundary
condition and its high-order compatible specular boundary condition. The proof is based on extra dissipation generated from semigroup method and energy estimates on electrostatic field.
