摘 要：The quasi-neutral limit of the Navier-Stokes-Poisson system with vanishing viscosity coefficients in the half-space is rigorously proved under a Navier-slip boundary condition for velocity and Dirichlet boundary condition for electric potential. This is achieved by establishing the nonlinear stability of the approximation solutions involving the strong boundary layer, which comes from the break-down of the quasineutrality near the boundary.
