摘要：
We establish the global existence of classical solutions to the Cauchy problem for the Navier-Stokes equations with viscosities depending on density in three spatial dimensions with smooth initial data which are of small energy but possibly large oscillations with constant state. Moreover, we obtain some large-time behavior and decay rate estimates of the solutions. Published under license by AIP Publishing.
