In 2019 McCleary and Patel proposed a generalization of a persistence diagram for a `multi-parameter filtration' of chain complexes of an abelian category as the Möbius inversion of the rank function of the associated `birth-death-(sub)object.' At the 2019 CMS winter meeting Patel spoke at the TDA session about this work and mentioned how he thought of Möbius inversion as a derivative. This poster shows how to (extend and then) view a certain quotient object in their work as a change-action derivative in the sense of Alvarez-Picallo and Lemay.

Joint work with Dr. Kristine Bauer (University of Calgary).
