Large time behaviors of the isentropic bipolar compressible Navier-Stokes-Poisson system
چکیده انگلیسی

The isentropic bipolar compressible Navier-Stokes-Poisson (BNSP) system is investigated in R3 in the present paper. The optimal time decay rate of global strong solution is established. When the regular initial data belong to the Sobolev space Hl(R3)∩ with l≥4 and s∈(0,1], it is shown that the momenta of the charged particles decay at the optimal rate (1+t)-14-s2 in L2-norm, which is slower than the rate (1+t)-34-s2 for the compressible Navier-Stokes (NS) equations [14]. In particular, a new phenomenon on the charge transport is observed. The time decay rate of total density and momentum was both (1+t)-34 due to the cancellation effect from the interplay interaction of the charged particles.
