Das Jacobische dreifache Produkt kann folgendermaßen formuliert werden: \[ (t;q)_ \infty\cdot (t^{-1} q;q)_ \infty\cdot (q;q)_ \infty= \sum^ \infty_{n=-\infty} (-1)^ n q^{{n\choose 2}} t^ n, \] wobei \((x; q)_ 0=1\) und \((x;q)_ n= (1-x)(1- xq)\cdots (1- xq^{n-1})\) ist. In diesem Artikel wird mittels der Durfee-Rechtecke der Partitionen ein sehr elementarer Beweis für die Identität des Jacobischen dreifachen Produkts sowie der endlichen Analoga vorgelegt. Schließlich wird ein Beispiel angeführt.
