非幺模横齐叶理

Non-unimodular transversely homogeneous foliations

E. Macías-Virgós, P. L. Martín-Méndez

摘要:

通过计算横齐次叶理的类基上同调,给出了其紧性的充分条件。作为应用,我们证明了如果叶理是非么模的,那么要么环境流形,关闭的叶子或全空间的一个相关的主丛纤维在$S^1$。

英文摘要:

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 $S^1$.
