Persistence Partial Matchings Induced by Morphisms between Persistence Modules
share
The notion of persistence partial matching, as a generalization of partial matchings between persistence modules, is introduced. We study how to obtain a persistence partial matching 𝒢_f, and a partial matching ℳ_f, induced by a morphism f between persistence modules, both being linear with respect to direct sums of morphisms. Some of their properties are also provided, including their stability after a perturbation of the morphism f, and their relationship with other induced partial matchings already defined in TDA.
