Axisymmetric Solutions of the 3-D Navier-Stokes Equations for Compressible
S. Jiang and P. Zhang
We prove the existence of global weak solutions to the Navier-Stokes
equations for compressible isentropic fluids for any $\gamma > 1$
when the Cauchy data are axisymmetric, where $\gamma$ is the
specific heat ratio. Moreover, we obtain a new integrability
estimate of the density in any neighborhood of the symmetric
axis (the singularity axis).
