三维不可压Euler流的几何性质与不爆破

Geometric properties and non-blowup of 3-D incompressible Euler flow

Jian Deng, Thomas Y. Hou, Xinwei Yu

摘要:

通过探讨涡量场沿涡丝的局部几何性质,我们建立了涡量场的几何性质和最大涡拉伸之间的尖锐关系。这一新的认识导致改进的结果的整体存在的3-D欧拉方程下温和的假设是一致的观察,从最近的数值计算。

英文摘要:

By exploring a local geometric property of the vorticity field along a vortex filament, we establish a sharp relationship between the geometric properties of the vorticity field and the maximum vortex stretching. This new understanding leads to an improved result of the global existence of the 3-D Euler equation under mild assumptions that are consistent with the observations from recent numerical computations.
