Just below equation (15), I think that it should be
$$\frac{\rho^2 P''+2\rho P'+\lambda \rho^2 P}{P}+
\frac{\Lambda Y }{Y}=0$$
Instead of:
$$\frac{\rho^2 P''+2\rho P'+\lambda P}{\rho^2 P}+
\frac{\Lambda Y }{Y}=0$$
If not, equation (16) would not follow
$$\rho^2 P''+2\rho P'+(\lambda \rho^2 - l(l+1) )P=0.$$

Minor typo at the end of Theorem 2
It should be $m=-l,1-l,\ldots,l-1,l$ not $m=-l,1-l,\ldots,l-1,m $
