Diffusion Wave for Navier-Stokes Equations in Even Space Dimensions
偶数维空间 Navier-Stokes 方程的扩散波

The authors study the large time behavior of solutions to general Navier-stokes equations in even space-dimension.Through the pointwise estimate of the Green function of the linearized system,the authors obtain explicit expressions of the time-asymptotic behavior of the solutions.The result coincides with weak Huygen's principle.
