Abstract: |
This paper is concerned with the Cauchy problem of the one-dimensional isothermal compressible Navier-Stokes-Korteweg system when the viscosity coe-cient and capillarity coe-cient are general smooth functions of the density. By using the elementary energy method and Kanel's technique[25], we obtain the global existence and time-asymptotic behavior of smooth non-vacuum solutions with large initial data, which improves the previous ones in the literature. |
