Abstract:
In this paper, we establish the existence of a global classical solution to 3D Cauchy problem of the isentropic compressible Navier-Stokes equations with large initial data and vacuum under the assumption that〖（\gamma;-1）〗^(1/6) 〖E_0〗^(1/2) \mu;^((-1)/2) is suitably small. It is showed that the initial energy E_0 can be large if the adiabatic exponent γ is near 1 or the viscosity coefficient μ is taken to be large.
