Local Existence Study Of Weak Solutions For Isentropic Compressible NAVIER-STOKES-POISSON Equations

This paper is concerned with the weak solution of the barotropic compressible Navier-Stokes-Poisson equations to the Cauchy problem.We mainly use energy estimation,Desjardin estimation method,the method of Hoff calculation and Huang-Yan estimation method.What we get is that there exists T0 ?(0,+?)and a weak solution(?,u,?)to the Navier-Stokes-Poisson equations in(0,T0).
