ist_product_table.m

Structure coefficient tables for the associative envelopes of su(mult) algebras.

Syntax

    [product_table_left,product_table_right]=ist_product_table(mult)

Arguments

    mult      - multiplicity of the spin in question

Outputs

Output contains the structure coefficients in the following conventions:

 product_table_left(n,m,k)=trace(T{n}*T{m}*T{k}')/...
                           sqrt(trace(T{k}*T{k}')*trace(T{m}*T{m}'))
   
 product_table_right(n,m,k)=trace(T{m}*T{n}*T{k}')/...
                            sqrt(trace(T{k}*T{k}')*trace(T{m}*T{m}'));

corresponding to Eq 7.18 of the first edition of IK's book (normalisation is missing in the book, that's a typo).

Notes

These are expensive tables: disk cache is created and used automatically.
