Abstract

We prove some vanishing theorems for the Kohn–Rossi cohomology of some spherical CR manifolds. To this end, we use a canonical contact form defined via the Patterson–Sullivan measure and Weitzenböck-type formulae for the Kohn Laplacian. We also see that our results are optimal in some cases.

球 CR 流形的 Kohn-Rossi 上同调

摘要

我们证明了一些球 CR 流形的 Kohn-Rossi 上同调的一些消失定理。为此,我们使用通过 Patterson-Sullivan 测度和 Kohn Laplacian 的 Weitzenböck 型公式定义的规范接触形式。我们还发现,在某些情况下我们的结果是最优的。
