What $Re(f(z))=c$ can be if $f$ is a holomorphic function ?

Suppose that $f:U\subset\mathbb{C}\to\mathbb{C}$, where $U$ is a region in the complex plane, is a holomorphic function. Of course, if $c\in\mathbb{R}$ is a regular value for $\text{Re}(f(z))$ then …

Coefficients of holomorphic functions defined by Borel probability measures on the unit disc

Let be $\mathcal M(\partial\mathbb D)$ denote the set of all Borel complex probability measures on $\partial\mathbb D$ (unit circle in the complex plane). Define a mapping $\Phi:\mathcal M(\partial\ma …
