摘要: 该文考虑偶数维空间一般 Navier-Stokes方程解的大时间状态.通过研究相应线性方程格林函数的逐点估计, 得到了解的渐近状态.所得结论与弱惠更斯原理相符合.

关键词: 一般 Navier-Stokes 方程, 偶数维空间, 大时间状态

Abstract: 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.

Key words: General Navier-Stokes equation, Even multi-dimension, Large time behavior
