论文摘要
我们介绍和研究翻译编号,用于主体$ \ mathbb {z} $ - 捆绑和平坦的princive $ \ mathbb {r} $ - 捆绑的自动形态。我们使用它们来显示出特征性的叶状束类别的消失结果,并检测束束自动形态的不合适元素。
We introduce and study translation numbers for automorphisms of principal $\mathbb{Z}$-bundles and flat principal $\mathbb{R}$-bundles. We use them to show a vanishing result of a characteristic class of foliated bundles and to detect undistortion elements in the group of bundle automorphisms.
