Functor morphing and representations of automorphism groups of modules

Key Points

The study reveals a hierarchical structure for automorphism groups of finite modules, enabling easier analysis of their representations.
It presents a method that exploits symmetric monoidal categories to decompose irreducible representations into manageable parts.
Our findings highlight the role of invariant theory in understanding the complexities of these representations.
This approach could significantly enhance future research on module theory and representation theory in mathematics.

Abstract

We introduce a strategy to study irreducible representations of automorphism groups of finite modules over finite rings. We prove that these automorphism groups fit in a hierarchy that facilitates a stratification of their irreducible representations in terms of smaller building blocks using symmetric monoidal categories and invariant theory.
