Global existence of solutions for compressible Navier–Stokes equations with vacuum

AbstractIn this paper, we will investigate the global existence of solutions for the one-dimensional compressible Navier–Stokes equations when the density is in contact with vacuum continuously. More precisely, the viscosity coefficient is assumed to be a power function of density, i.e., μ(ρ)=Aρθ, where A and θ are positive constants. New global existence result is established for 0<θ
