内 容 介 绍：Compressible Navier-Stokes equations with density dependent viscosity arises from many physical applications, say, geophysical flows. When initial density does not have a uniformly positive lower bound, the local well-posedness of classical solutions has been open for long time. We survey some of our recent progress on this direction. When viscosity coefficients are constant multiple of a power of density, we identify the class of initial data admitting a local classical solution local in time when the power is greater or equal to 1. The questions on the singularity formation will also be addressed. This talk is mainly based on joint works with Y. Li,and S. Zhu.
