Temperley-Lieb Algebra

Definition

The Temperley-Lieb algebra is a specific type of algebraic structure that arises in the study of planar diagrams and is connected to knot theory and statistical mechanics. It consists of linear combinations of diagrams that represent certain relations, making it an important tool for understanding the connections between algebra, geometry, and topology, particularly in the context of planar algebras.
