论文摘要
在边界层剖面上的轻度凹凹条件下,我们为一般边界层扩展提供了最佳的Gevrey稳定性结果。我们的结果概括了(甚至在非严格凹形案例中)在[Gerard-Varet等人,Duke Math中获得的案例。 J. 167(2018)],仅限于剪切流类型的扩展。
We provide an optimal Gevrey stability result for general boundary layer expansions, under a mild concavity condition on the boundary layer profile. Our result generalizes (and even improves in the non strictly concave case) the one obtained in [Gerard-Varet et al, Duke Math. J. 167 (2018)], restricted to expansions of shear flow type.
