Multiparameter persistence modules in the large scale

Algebraic Topology 2026-05-22 v4 Representation Theory

Abstract

A persistence module with mm discrete parameters is a diagram of vector spaces indexed by the poset Nm\mathbb{N}^m. If we are only interested in the large scale behavior of such a diagram, then we can consider two diagrams equivalent if they agree outside of a ``negligeable'' region. In the 22-dimensional case, we classify the indecomposable diagrams up to finitely supported diagrams. In higher dimension, we partially classify the indecomposable diagrams up to suitably finite diagrams, and show that the full classification problem is wild.
