绷紧叶理

Taut foliations

William H. Kazez, Rachel Roberts

摘要:

我们描述的概念,在$C^0$叶理,$C^{1,0}$或更平滑的叶理,并在几何研究中出现的紧。我们给出的例子表明,这些概念是不同的,并讨论这些差异如何影响一些经典的叶理结果。我们构造了光滑绷紧的$C^{\infty,0}$叶理的例子,这些叶理可以用弱辛可填充的、普遍紧的切触结构和过扭曲的切触结构来近似$C^0$。

英文摘要:

We describe notions of tautness that arise in the study of $C^0$ foliations, $C^{1,0}$ or smoother foliations, and in geometry. We give examples to show that these notions are different, and discuss how these differences impact some classical foliation results. We construct examples of smoothly taut $C^{\infty,0}$ foliations that can be $C^0$ approximated by both weakly symplectically fillable, universally tight contact structures and by overtwisted contact structures.
