@A.G. Oh yeah, I'm sorry, I have missed a condition.

comment Prove that there exists an analytic function $g$ such that derivative takes maximum
@DavidC.Ullrich Thanks! And when I know the local boundedness, I should apply Montel. And note that the derivative of a normal family is also normal, thus $\mathcal{F}'''$ is normal! It's a pity that I totally missed this this afternoon...

comment Prove that there exists an analytic function $g$ such that derivative takes maximum
@DavidC.Ullrich Yeah, just use the Mobius transform $\frac{z-1}{z+1}$, and then use Montel to show that $\mathcal{F}$ is a normal family, and thus $\mathcal{F}'''$ is a normal family?

comment Curvature for tautological bundle of projectivation
Thanks! So if I use $h(z,z)=\sum_{i,j} h^{ij} z_i \bar{z}_j$, then the holomorphic section is then $\frac{1}{h^{jj} z_j \bar{z_j}}\sum_{i,j} h^{ij} z_i \bar{z}_j$?
