Abstract
A new method for calculation of Clebsch-Gordan coefficients (CGCs) of the Lie algebrau(n) and its quantum analogU .sub.q(u(n)) is developed. The method is based on the projection operator method in combination with the Wigner-Racah calculus for the subalgebrau(n-1) (U .sub.q(u(n-1))). The key formulas of the method are couplings of the tensor and projection operators and also a tensor form of the projection operator ofu(n) andU .sub.q(u(n)). It is shown that theU .sub.q(u(n)) CGCs can be presented in terms of theU .sub.q(u)(n-1)) q-9j-symbols.
