Wiener混合空间中Navier-斯托克斯方程的局部能量解

Local energy solutions to the Navier-Stokes equations in Wiener amalgam spaces

Zachary Bradshaw, Tai-Peng Tsai

摘要:

我们建立了一个规模的类弱于有限能量Leray类和强于无限能量Lemarié-Rieusset类的解的存在性。新的类是基于$L^2$ Wiener汞齐空间。类中的解决方案更接近Leray类中所示,以满足一些已知的性质,在Leray类,但不是Lemarié-Rieusset类,即最终的规律性和长期估计的增长,当地的能源。从这个意义上说,这些解弥补了勒雷原始解和Lemarié-Rieusset解之间的差距,并有助于确定某些性质可能崩溃的标度。

英文摘要:

We establish existence of solutions in a scale of classes weaker than the finite energy Leray class and stronger than the infinite energy Lemarié-Rieusset class. The new classes are based on the $L^2$ Wiener amalgam spaces. Solutions in the classes closer to the Leray class are shown to satisfy some properties known in the Leray class but not the Lemarié-Rieusset class, namely eventual regularity and long time estimates on the growth of the local energy. In this sense, these solutions bridge the gap between Leray's original solutions and Lemarié-Rieusset's solutions and help identify scalings at which certain properties may break down.
