WebJun 23, 2024 · In your case, both your Lie algebras are Lie subalgebras of $\mathfrak{su}(2)$, and since $\mathfrak{u}(1)$ commutes with all of $\mathfrak{su}(2)$, its generator will too. Remember that $\mathfrak{u}(1)$ is just the non-zero complex numbers, so it makes sense that they commute with all matrices.
