Module structure

Definition

Module structure refers to a way of organizing and understanding algebraic structures known as modules, which generalize vector spaces by allowing scalars to come from a ring instead of just a field. This concept provides a framework for analyzing the relationships and properties of modules, especially in the context of Malcev algebras where modules are pivotal for exploring their structure and representation theory.
