So, to understand correctly, $I_{j_{1}j_{2}}^{j_{3}}$ in your notation is the (unique up to multiple) intertwiner of the form $I_{j_{1}j_{2}}^{j_{3}}:V_{j_{3}}\to V_{j_{2}}\otimes V_{j_{2}}$ and hence, using your formula, the matrix coefficients of this intertwiner are exactly given by $(-1)^{-j_{1}+j_{2}+m_{3}}\sqrt{2j_{3}+1}$ times the $3j$-symbol? | |
