在本文中,我们在环形区域b2 (0) × b1(0)∧r2中,在二维泰勒-库埃特流和类似单调流周围建立具有最佳衰减率的线性无粘阻尼。根据Wei, Zhang和Zhao[10]最近的结果,我们建立了加权规范的稳定性,它允许在边界处形成奇点,并且另外提供了爆炸行为的描述。
In this article we establish linear inviscid damping with optimal decay rates around 2D Taylor–Couette flow and similar monotone flows in an annular domain B r 2 (0)∖ B r 1 (0)⊂ R 2. Following recent results by Wei, Zhang and Zhao [10], we establish stability in weighted norms, which allow for a singularity formation at the boundary, and additionally provide a description of the blow-up behavior.
