<p>first draft</p> <p><b>New page</b></p><div>A parabolic fixpoint is a [[fixpoint]] $p$ of a function $f$ such that $f&#039;(p)=1$.<br /> In some literature also a [[fixpoint]] $p$ with $f&#039;(p)=e^{2\pi i q}$, $q\in \Q$ is called parabolic, because there is some $m\in\Z$ such that $(f^m)&#039;(p)=1$ (remember $(f^m)&#039;(p)=f&#039;(p)^m=e^{2\pi i qm}$).</div>
