$n$点上的持久图空间粗嵌入希尔伯特空间

The Space of Persistence Diagrams on $n$ Points Coarsely Embeds into Hilbert Space

Atish Mitra, Žiga Virk

摘要:

通过证明$n$点上的持久图空间具有渐近维数$2n$,证明了$n$点上的持久图空间(具有瓶颈或Wasserstein距离)粗嵌入希尔伯特空间.这样的嵌入使得能够在持久性图的空间上利用希尔伯特空间技术。我们还证明了当点的个数没有界时,相应的持久图空间没有有限的渐近维数。此外,在瓶颈距离的情况下,相应的空间不粗嵌入到希尔伯特空间。

英文摘要:

We prove that the space of persistence diagrams on $n$ points (with the bottleneck or a Wasserstein distance) coarsely embeds into Hilbert space by showing it is of asymptotic dimension $2n$. Such an embedding enables utilisation of Hilbert space techniques on the space of persistence diagrams. We also prove that when the number of points is not bounded, the corresponding spaces of persistence diagrams do not have finite asymptotic dimension. Furthermore, in the case of the bottleneck distance, the corresponding space does not coarsely embed into Hilbert space.
