论文摘要

我们通过计算其基础样的共同体学,为在紧凑型歧管上定义的横向同质叶片的拉紧提供了足够的条件。作为一种应用,我们证明,如果叶面不占据,则环境歧管,叶子的闭合或相关的主束纤维超过$ s^1 $的总空间。

We give sufficient conditions for the tautness of a transversely homogenous foliation defined on a compact manifold, by computing its base-like cohomology. As an application, we prove that if the foliation is non-unimodular then either the ambient manifold, the closure of the leaves or the total space of an associated principal bundle fiber over $S^1$.
