摘要

Pittie（Proc Indian Acad Sci Math Sci 98:117-1521988）证明了紧致李群上所有左不变复结构的Dolbeault上同调可以通过观察在方便选择的最大环面上诱导的Dolbeaut上同调来计算。我们将Pittie的结果推广到紧致李群上最大秩的左不变Levi平坦CR结构。我们使用的主要工具是CR主丛的Leray–Hirsch定理的一个版本，以及紧李群上最大秩的左不变CR结构的代数分类（Charbonnel和Khalgui在J Lie Theory 14:165-1982004中）。

Levi-flat CR structures on compact Lie groups

Pittie (Proc Indian Acad Sci Math Sci 98:117-152, 1988) proved that the Dolbeault cohomology of all left-invariant complex structures on compact Lie groups can be computed by looking at the Dolbeault cohomology induced on a conveniently chosen maximal torus. We generalized Pittie’s result to left-invariant Levi-flat CR structures of maximal rank on compact Lie groups. The main tools we used was a version of the Leray–Hirsch theorem for CR principal bundles and the algebraic classification of left-invariant CR structures of maximal rank on compact Lie groups (Charbonnel and Khalgui in J Lie Theory 14:165-198, 2004) .

期刊介绍： This journal examines global problems of geometry and analysis as well as the interactions between these fields and their application to problems of theoretical physics. It contributes to an enlargement of the international exchange of research results in the field. The areas covered in Annals of Global Analysis and Geometry include: global analysis, differential geometry, complex manifolds and related results from complex analysis and algebraic geometry, Lie groups, Lie transformation groups and harmonic analysis, variational calculus, applications of differential geometry and global analysis to problems of theoretical physics.
