|Rips magnitude||Dejan Govc
Govc: Magnitude is a numerical invariant of metric spaces (and
more generally, enriched categories) introduced by Tom Leinster which
has been shown to arise as the graded Euler characteristic of a
certain homology theory. Richard Hepworth has recently suggested to
examine an analogous invariant for persistent homology, called Rips
magnitude, which arises as a graded Euler characteristic of persistent
homology. In the talk I will describe some of its basic properties and
examine its asymptotic behaviour in the case of finite subsets of the
circle. This is joint work with Richard Hepworth.
