开流形的一种分类方法

A Classification Approach for Open Manifolds

Juergen Eichhorn

摘要:

开流形有至少不可数多个自同态类型。因此,分类问题非常困难。我们定义了真度量空间的几种一致结构,并考虑了它们的弧分量。任何开完备流形(M^n,g)定义了这样一个分支。因此,分类分为两个步骤。首先计算所有组件,然后计算组件中的所有元素。这可以部分地由不变量完成。定义了协边群和相对示性数。

英文摘要:

There are a least uncountably many diffeomorphism types for open manifolds. Hence the classification problem is extremely difficult. We proceed as follows: We define several uniform structures of proper metric spaces and consider their arc components. Any open complete manifold (M^n,g) defines such a component. Hence the classification amounts to two steps. First counting all components, and secondly counting all elements inside a component. This can be partially done by invariants. We define bordism groups and relative characteristic numbers.
