几何学中的外丛

Exterior bundles in diffeology

J. Daniel Christensen, Enxin Wu

摘要:

我们探讨了几个概念的$k$ -形式在一个点上的拓扑空间,构建这样的$k$ -形式的丛,并比较这些束的部分微分形式。由于它们是局部定义的,我们的$k$ -形式可以包含比微分形式包含的值更多的信息,我们用许多例子来说明这一点。为了组织我们的工作,我们开发的基本理论的拓扑向量伪丛,包括详细了解其限制和colimits,以及各种纤维操作,如产品,直和,张量积,外部电源和对偶丛。

英文摘要:

We explore several notions of $k$-form at a point in a diffeological space, construct bundles of such $k$-forms, and compare sections of these bundles to differential forms. As they are defined locally, our $k$-forms can contain more information than the values of differential forms contain, and we illustrate this with many examples. To organize our work, we develop the basic theory of diffeological vector pseudo-bundles, including a detailed understanding of their limits and colimits, as well as a variety of fibrewise operations such as products, direct sums, tensor products, exterior powers and dual bundles.
