Abstract:We generalize a result of Giroux which says that a closed surface in a contact $3$-manifold with Morse-Smale characteristic foliation is convex. Specifically, we show that the result holds in contact manifolds of arbitrary dimension. As an application, we show that a particular closed hypersurface introduced by A. Mori is $C^{\infty }$-close to a convex hypersurface.

接触流形中的 Morse-Smale 特征叶面和凸度

摘要:我们概括了 Giroux 的结果,该结果表明,具有 Morse-Smale 特征叶理的接触 $3$-流形中的闭合曲面是凸面。具体来说,我们表明该结果适用于任意维度的接触流形。作为一个应用,我们展示了由 A. Mori 引入的特定封闭超曲面是 $C^{\infty }$-接近凸超曲面。
