旋转不变Navier-Stokes流的时空衰减

Space-time decay of Navier-Stokes flows invariant under rotations

Lorenzo Brandolese

摘要:

我们表明,解决方案的非定常斯托克斯方程在$R^d$,$d=2,3$的正交群$O(d)$的离散子群的作用下是左不变的衰减快得多的$|x|\to\infty$或$ t \to\infty$比一般情况下,我们计算,为每个子组,精确的衰减率在时空中的速度场。

英文摘要:

We show that the solutions to the non-stationary Navier-Stokes equations in $R^d$, $d=2,3$ which are left invariant under the action of discrete subgroups of the orthogonal group $O(d)$ decay much faster as $|x|\to\infty$ or $ t \to\infty$ than in the generic case and we compute, for each subgroup, the precise decay rates in space-time of the velocity field.
