摘要

我们证明了有界域中临界耗散 SQG 方程全局平稳解的存在性和唯一性。我们引入了一种新方法，将有界域中的单一非局部非线性演化方程转化为整个空间中的扩展非局部非线性演化方程的相互作用系统。然后利用扩展系统中的非局部算子的非线性最大原理方法进行证明。

Global regularity for critical SQG in bounded domains

We prove the existence and uniqueness of global smooth solutions of the critical dissipative SQG equation in bounded domains in . We introduce a new methodology of transforming the single nonlocal nonlinear evolution equation in a bounded domain into an interacting system of extended nonlocal nonlinear evolution equations in the whole space. The proof then uses the method of the nonlinear maximum principle for nonlocal operators in the extended system.
