I found this result for so (3) by showing that given the usual basis of so (3), F1, F2, F3, the lie bracket relations for basis elements are: [F1, F2]=F3, [F1,F3]=F2, [F3,F2]=F1. Thus the form of matrices is preserved by the ... WebThe representations of the group lie in the 2-dimensional I 3 −Y plane. Here, ^ stands for the z-component of Isospin and ^ is the Hypercharge, and they comprise the (abelian) Cartan subalgebra of the full Lie algebra.
