| Research Abstract |
We study a free boundary problem for compressible spherically symmetric Navier-Stokes equations or Navier-Stokes-Poisson equation with degenerate viscosity coefficients and with or without a solid core. The two papers said that under certain assumptions on the initial data, the global existence and uniqueness of the weak solution are obtained and that solution has some uniform bounds.
