具有混合部分粘性和热扩散系数的二维非线性Boussinesq方程的整体适定性

Global well-posedness of 2D nonlinear Boussinesq equations with mixed partial viscosity and thermal diffusivity

Chao Chen, Jitao Liu

摘要:

讨论了具有任意两个正粘性系数和一个正热扩散系数的二维各向异性非线性Boussinesq方程的整体适定性.更准确地说,对于三种粘性组合,我们得到了整体适定性没有任何假设的解决方案。对于其他三种困难情形,在最小正则性假设下,我们也得到了唯一的整体解。据作者所知,我们的结果是新的,即使在简化模型。

英文摘要:

In this paper, we discuss with the global well-posedness of 2D anisotropic nonlinear Boussinesq equations with any two positive viscosities and one positive thermal diffusivity. More precisely, for three kinds of viscous combinations, we obtain the global well-posedness without any assumption on the solution. For other three difficult cases, under the minimal regularity assumption, we also derive the unique global solution. To the authors' knowledge, our result is new even for the simplified model.
