Persistent homology is an important tool in topological data analysis, whose goal is to quantify and learn from the `shape' of data. First we encode scientific data as a diagram of spaces and then we apply a homology functor to obtain a diagram in an abelian category. In nice cases, this diagram can be represented by a formal sum in a pointed metric space. I will show how categorical constructions give us a family of distances on these formal sums.

Joint work with Alex Elchesen (University of Florida, USA).
