弹性拓扑空间

Elastic diffeological spaces

Christian Blohmann

摘要:

本文引入了一类称为弹性空间的拓扑空间,在这类空间上,光滑流形的切函子的左Kan扩张定义了Rosicky意义下的抽象切函子.在弹性空间上有一个自然的Cartan演算,它由向量场和微分形式组成,以及李括号、德拉姆微分、内导数和李导数,满足通常的分次对易关系。弹性空间在任意余积、有限积和收缩下是封闭的。例子包括具有角和尖点的流形,具有温和额外条件的拓扑群和拓扑向量空间,光滑流形之间的映射空间,以及光滑纤维丛的截面空间。本文是一个较长的工作的浓缩预览,解释其动机,主要概念和结果,但省略了大部分的证明。

英文摘要:

We introduce a class of diffeological spaces, called elastic, on which the left Kan extension of the tangent functor of smooth manifolds defines an abstract tangent functor in the sense of Rosicky. On elastic spaces there is a natural Cartan calculus, consisting of vector fields and differential forms, together with the Lie bracket, de Rham differential, inner derivative, and Lie derivative, satisfying the usual graded commutation relations. Elastic spaces are closed under arbitrary coproducts, finite products, and retracts. Examples include manifolds with corners and cusps, diffeological groups and diffeological vector spaces with a mild extra condition, mapping spaces between smooth manifolds, and spaces of sections of smooth fiber bundles. This paper is a condensed preview of a longer work, explaining its motivation, main concepts, and results, but omitting most of the proofs.
