show univalent $g(z)=z+c_{n+1}z^{n+1}+c_{2n+1}z^{2n+1}+c_{3n+1}z^{3n+1}+\cdots$ can be written $g(z)=\sqrt[n]{f(z^n)}$ with $f$ univalent Show that the univalent function $$g(z)=z+c_{n+1}z^{n+1}+c_{2n+1}z^{2n+1}+c_{3n...
You have $g(z)=zh(z^n)$ and $f(z)=zh(z)^n$ (for the evident $h$). Now if $f(z)=f(w)$ (for some $z,w$), i.e. $zh(z)^n=wh(w)^n$ then $z^{1/n}h(z)=w^{1/n}h(z)$ for _some_ choice of $z^{1/n},w^{1/n}$, i.e. $g(z^{1/n})=g(w^{1/n})$, so $z^{1/n}=w^{1/n}$ and thus $z=w$.

complex analysis (Univalent function ) The Distortion Theorem tells us that if $f$ is a univalent function on $\mathbb{D}:=\\{z:|z|<1\\}$, then $|f'(z)|\leq 12\,|f'(0)|$ for $|z|\leq\frac12$. By iterating this, prove ...
Gah, what a horribly wasteful way to estimate the derivative. You are basically asked to go from $z$ to $w$ in horizontal steps. This is not how one should move about in the half-plane model of hyperbolic plane. Oh well. Begin with the estimate $$|f'(\zeta)|\le 12 |f'(z)|,\qquad\text{where }\ |z-\ze...

Univalent function with parameter. Let $a, b, z_0 \in \mathbb{C}$. Find the highest value R, at which the function: $f(z) = z^2 + az + b$ is univalent in the disk: $|z - z_0| < R$ I use the definition of univalent fun...
You are not on the right track. The derivative of $f(z)$ is $f'(z) = 2z+a$, which is zero at the point $z_1 = -a/2$. Hence the highest value of $R$ is at most $R = |z_1-z_0|$. On the other hand it is easy to see that the function is injective on the region $$ U = \\{ z : |z - z_0| < |z_1 - z_0| \\},...
