Braiding

Definition

Braiding refers to a mathematical concept that involves intertwining elements in a way that creates a specific structure, often seen in the context of representations of quantum groups. It reflects the idea of how objects can be related to each other through nontrivial interlacing, and this property is essential for understanding how representations behave under various transformations and symmetries.
