Looking at these solutions with our constraints for $$R_o$$ in mind,
we see that for $$\mu > 0$$ none of the solutions decay
*monotonically* to zero, so we must have $$\mu \le 0$$ in the cladding.

This shows that each $$\mathrm{LP}_{\ell m}$$ has an associated cut-off $$V_{\ell m}$$,
so that if $$V > V_{\ell m}$$ then $$\mathrm{LP}_{lm}$$ exists,
