关于多元Burgers方程和不可压斯托克斯方程(III部分)

On the multivariate Burgers equation and the incompressible Navier-Stokes equation (part III)

Joerg Kampen

摘要:

本文首先得到了一个局部格式在关于时间和空间的Hm-范数下的局部收缩结果。我们表明,一个全球性的控制计划保持更高的秩序的规律性与多项式衰减的数据在每个时间步的空间变量。这里,我们简化了[1]和[2]中考虑的控制方案。特别地,对于简化控制方案,我们得到了Leray投影项的上界。此外,文[1]和[2]中讨论的格式在某种意义上是简化的,即在不使用关于具有可变漂移项的局部基本解的伴随的某些性质的情况下,得到了估计。我们注意到,局部泛函级数及其一阶时间导数和空间导数的逐点和绝对收敛性导致了局部和整体经典解的构造性方法.

英文摘要:

In this paper we first obtain local contraction results in a Hm-norm with respect to time and space for a local scheme. We show that a global controlled scheme preserves higher order regularity with respect to the spatial variables together with polynomial decay of order m of the data at each time step. Here, we simplify the controlled scheme considered in [1] and [2]. Especially, for the simplified controlled scheme we get an upper bound for the Leray projection term. Furthermore, the schemes discussed in [1] and [2] are simplified in the sense that the estimates are achieved without the use of some properties concerning the adjoint of a local fundamental solutions with variable drift terms. We note that the pointwise and absolute convergence of the local functional series and their first order time derivatives and their spatial derivatives leads to a constructive approach of local and global classical solutions.
