Abstract:

Given a metric pair $(X,A)$, i.e. a metric space $X$ and a distinguished closed set $A\subset X$, one may construct in a functorial way a pointed pseudometric space $\mathcal {D}_\infty (X,A)$ of persistence diagrams equipped with the bottleneck distance. We investigate the basic metric properties of the spaces $\mathcal {D}_\infty (X,A)$ and obtain characterizations of their metrizability, completeness, separability, and geodesicity.
