 installiert sein.
 Ein 
\noun on

-Diagramm wird erzeugt, indem der Befehl 
\series bold

 in eine Formel eingegeben wird.
 Man kann anschließend neue Matrix-Spalten und Zeilen wie bei normalen Matrizen
 einfügen.

 Wenn Ihr Dokument ein Stichwortverzeichnis hat und eine der AMS Theorem-Module
 verwendet wird, muss die Option 
\series bold

\series default
 zu den Dokumentklassenoptionen in den Dokument-Einstellungen hinzugefügt
 werden.
 Dies ermöglicht die Verwendung des Zeichens '!' in Stichworten (wird für
 Untereinträge benötigt), kann aber zu Problemen mit den Align-Umgebungen
 führen (die im Abschnitt
