U( n) Wigner coefficients, the path sum formula, and invariant G-functions

We prove the path sum formula for computing the U( n) invariant denominator functions associated to stretched U( n) Wigner operators. A family of U( n) invariant polynomials G [ λ] ( n) is then defined which generalize the μ G q ( n) polynomials previously studied. The G [ λ] ( n) polynomials are sh...
