Temperley-Lieb algebra
From Wikipedia, the free encyclopedia
In statistical mechanics, the Temperley-Lieb algebra is an algebra generated by certain transfer matrices, invented by Temperley and Lieb in about 1971. It is also related to knot theory, the braid group, and subfactors of von Neumann algebras.
[edit] Definition
The Temperley-Lieb algebra is generated by elements en for n≥1 subject to the following relations:
- en2=en
- emen=enem if |m-n|>1.
- en+1enen+1= τen+1
- enen+1en= τen
