McGrew Asks: What is knotted in EM and GR? I am more interested in what you can do when there is no isomorphism to $SU(N)$. I am not that interested in $SO(6)$ results as it is basically similar to $SO(3)$ in that you can just use $SU(N)$ techniques.
If we stick with just fundamental for a second what would happen when we take the tensor product with a third (and forth etc.) fundamental representation? This says that the fundamental representation always can be decomposed in terms of traceless, symmetric traceless and antisymmetric representations for all $SO(N)$. I already found this this very useful result in another answer (last part).
How do I take a tensor products of $SO(N)$ irreps and decompose it in terms of irreps for $N>3$? (I understand the special case of $SO(3)$ we can use the nice $SU(N)$ technology of Young Tableauxs but I am not interested in that case).Īre there general procedures? If not are there procedures that work for specific representations (fundamental, adjoint ,something else.)?
