Multi-parameter persistence modules do not admit barcodes--unlike their widely used one-parameter analogues in topological data analysis—-, and more generally no complete and computationally manageable description. This thesis proposes to circumvent this obstacle through two approaches. The first consists of identifying subclasses of such modules that are indeed described by multi-sets of multi-parameter intervals. Keeping in mind the need to algorithmically test membership in these subclasses, we study the existence of those with a local characterization, i.e., those whose membership can be tested by observing only the restrictions of the persistence modules to finite subsets of the parameter space. We show that while the subclass of inter...
