Partial matchings induced by morphisms between persistence modules

We study how to obtain partial matchings using the block function Mf , induced by a morphism f between persistence modules. Mf is defined algebraically and is linear with respect to direct sums of morphisms. We study some interesting properties of Mf , and provide a way of obtaining Mf using matrix...

Sumario:We study how to obtain partial matchings using the block function Mf , induced by a morphism f between persistence modules. Mf is defined algebraically and is linear with respect to direct sums of morphisms. We study some interesting properties of Mf , and provide a way of obtaining Mf using matrix operations
