\bigskip \medskip

\item{\bf p86} Erste Zeile des Beweises von Satz 20.6:
$\bigcap_{S\le R, 1\in S} S =\Pi_R$.

\item{\bf p138} Zweite Zeile von unten: statt ${\rm deg}(q'-g)g$ 
geh\"ort ${\rm deg}(q'-q)g$. 

\item{\bf p139} Kor.\ 33.2, im letzten Absatz des Beweises soll es 
${\rm deg}(fg)\ge {\rm deg}(f)$ (nicht: $\le$) heissen.

\item{\bf p141} Bemerkung vor Lemma 34.3.: 
$f(x) = a_0 + a_1 x^p + a_2 x^{2p}$.

\item{\bf p164\ } Lemma\ 38.7. Statt $(m,n)$ soll es ${\rm ggT}(m,n)$
heissen.
