| Abstract: |
| In this paper, we establish a characterization of the mixed radial-angular $\lambda$-central bounded mean oscillation spaces via the boundedness of the commutators $\mathrm{H}_b$ and its dual $\mathrm{H}^*_b$ with a function $b\in {\mathrm{CMOL}^{p_2, \lambda}_{\rm rad}L^{p_1}_{\rm ang}(\mathbb R^n)}$. |
