摘要
This paper is to investigate the optimal L-p (p >= 2) time decay rate of global solutions to the two-fluid incompressible Navier-Stokes-Fourier-Poisson system with Ohm's law. The result shows that the time decay rate of this system achieves the same as that of the incompressible Navier-Stokes equation, in other words, the coupling of the self-consistent Poisson equation does not change the decay rate of the incompressible Navier-Stokes equation. This phenomenon is interesting, compared to the compressible Navier-Stokes equation, whose time decay rate decreases when it is coupled with the self-consistent Poisson equation.
