As I found it, branching rules are mainly concerned with behavior of irreducible representations restricted to Levi subgroups. The case $SO_3\subset SO_4$ should finally fall into this situation. And what about $SO_3\subset SL_3$? $SO_3$ is its own normalizer in $SL_3$, with trivial centralizer. In view of mathoverflow.net/questions/18764, it is not associated to a Dykin subdiagram for that of $SL_3$. I expect the situation to be different in this case. | |
