R-matrix

introduction

• R-matrix has entries from Boltzman weights.
• From quantum group point of view, R-matrix naturally appears as intertwiners of tensor product of two evaluation modules
• from this intertwining property we need to consider  \(\bar R=p\circ R\) instead of the \(R\) matrix where \(p\) is the permutation map
• this is what makes the module category into braided monoidal category

 

 

 

R-matrix and Braid groups

For \(R\) matrix on \(V \otimes V\), define \(\bar R=p\circ R\) where \(p\) is the permutation map.

\(\bar R_i=1\otimes \cdots \otimes\bar R \cdots \otimes 1\), \(\bar R_i\) sitting in i and i+1 th slot.

Then YB reduces to

\(\bar R_i\bar R_j =\bar R_j\bar R_i\) whenever \(|i-j| \geq 2 \)

\(\bar R_i\bar R_{i+1}\bar R_i= \bar R_{i+1}\bar R_i \bar R_{i+1}\)

which are the Braid group relations.
