Elements of Lie algebra are generators. So for example Pauli matrices are generators of rotation and the elements of Lie algebra. And multiplication in Lie algebra is commutator. Right?
What about if there is only one generator. As in case in rotation in plane. What is Lie algebra product in that case?
