拓扑空间的D-拓扑

The D-topology for diffeological spaces

J. Daniel Christensen, Gord Sinnamon, Enxin Wu

摘要:

拓扑空间是光滑流形的推广,它包括奇异空间和函数空间。对于每个拓扑空间,伊格莱西亚斯-泽穆尔引入了一个自然拓扑,称为$D$ -拓扑。然而,$D$ -拓扑尚未得到认真研究,在现有的文献。本文发展了拓扑空间的$D$ -拓扑的基本理论。我们解释了拓扑空间的$D$ -拓扑出现的正是$Δ$ -生成的空间,并给出结果和例子,这有助于确定当一个空间是$Δ$ -生成的。我们最实质性的结果显示如何PDMATHAMM-拓扑的函数空间$C^{\infty}(M,N)$之间的光滑流形相比,其他知名的拓扑。

英文摘要:

Diffeological spaces are generalizations of smooth manifolds which include singular spaces and function spaces. For each diffeological space, Iglesias-Zemmour introduced a natural topology called the $D$-topology. However, the $D$-topology has not yet been studied seriously in the existing literature. In this paper, we develop the basic theory of the $D$-topology for diffeological spaces. We explain that the topological spaces that arise as the $D$-topology of a diffeological space are exactly the $Δ$-generated spaces and give results and examples which help to determine when a space is $Δ$-generated. Our most substantial results show how the $D$-topology on the function space $C^{\infty}(M,N)$ between smooth manifolds compares to other well-known topologies.
