When a categorysatisfies certain conditions, we define the notion ofrank invariantfor arbitrary poset-indexed functorsfrom a category theory perspective. This generalizes the standard notion of rank invariant as well as Patel’s recent extension. Specifically, the barcode of any interval decomposable persistence modulesof finite dimensional vector spaces can be extracted from the rank invariant by the principle of inclusion-exclusion. Generalizing this idea allows freedom of choosing the indexing posetofin defining Patel’s generalized persistence diagram ofF. Of particular importance is the fact that the generalized persistence diagram ofFis defined regardless of whetherFis interval decomposable or not. By specializing our idea to zigzag persistence modules, we also show that the zeroth level set barcode of a Reeb graph can be obtained in a purely set-theoretic setting without passing to the category of vector spaces. This leads to a promotion of Patel’s semicontinuity theorem about typepersistence diagram to Lipschitz continuity theorem for the category of sets.
