8.22 Clebsch-Gordan coefficients (10.1.00)

8.22.1 Andrzej Pindor

Does anyone know about Maple procedures to calculate Clebsch-Gordan coefficients?

8.22.2 Alain Goupil (11.1.00)

I remember studying Clebsh-Gordan coefficients when I was Ph.D. student. Are these the coefficients in the decomposition of tensor product of irreducible representations.

If so which tensor product ? Exterior or interior (Kronecker) and for which group ?

There is the package SF(symmetric functions) that you can use to decompose tensor products of irreps of the symmetric group.

In the share library, there should be a worksheet called Wigner, which as I recall does do C-G coefficients and related calculations. If you can’t find it, I have a copy here on my PC.
