چکیده

Let P be a finite partially ordered set, briefly a finite poset. We will show that for any P -persistent object X in the category of finite topological spaces, there is a P− weighted graph, whose clique complex has the same P -persistent homology as X.

Persistent Homology of Finite Topological Spaces

We introduce homology and finite topological spaces. From the basis of that introduction, persistent homology is applied to finite spaces. We prove an equivalence between persistent homology and normal homology in the context of finite topological spaces and introduce an extended pseudometric on finite topological spaces, using the results of Minian.

Our main result is that, in a precise sense, the...

Persistent homology for metric measure spaces, and robust statistics for hypothesis testing and confidence intervals

We study distributions of persistent homology barcodes associated to taking subsamples of a fixed size from metric measure spaces. We show that such distributions provide robust invariants of metric measure spaces, and illustrate their use in hypothesis testing and providing confidence intervals for topological data analysis.

Some aspects of cosheaves on diffeological spaces

We define a notion of cosheaves on diffeological spaces by cosheaves on the site of plots. This provides a framework to describe diffeological objects such as internal tangent bundles, the Poincar'{e} groupoids, and furthermore, homology theories such as cubic homology in diffeology by the language of cosheaves. We show that every cosheaf on a diffeological space induces a cosheaf in terms of t...
