Aufgabensammlung zum Staatsexam in Algebra

Diese Seite enthät alle Staatsexamensaufgaben im Bereich Algebra für die Jahrgänge 2012 bis 2019 mit Lösungsvorschlägen, ab Herbst 2018 auch mit Kommentaren und Hinweisen versehen. Weiter unten finden Sie die Aufgaben nach Einzelthemen sortiert. Außerdem habe ich versucht, die Aufgaben nach dem Schwierigkeitsgrad einzuteilen (grün = standard, sollte keine bei Kenntnis des zu Grunde liegenden Stoffs keine Probleme bereiten, gelb = erfordert eine sichere Beherrschung des Stoffs und eventuell auch etwas Kreativität, rot = für Experten). Natürlich ist diese Einschätzung hochgradig subjektiv.

Eine alte Fassung der Seite finden Sie hier, sie enthält noch einige Lösungen von Aufgaben aus älteren Jahrgängen (vor 2012). Bitte beachten Sie, dass diese Seite von nun an nicht mehr aktualisiert wird.
