    Für die Funktion \[ f(x) = \prod\left\{1 + \frac x{n(\log n)^\alpha}\right\}\qquad \left(\begin{aligned} n = 2,3,\dots,\infty\\ 1 < \alpha < 2\end{aligned}\right) \] können angenäherte Ausdrücke der Wurzeln von \(f(x)-c\), \(f(x) + f(-x)\) fast unmittelbar aus dem bekannten asymptotischen Ausdrucke für \(f(x)\) erhalten werden. Diese Ausdrücke werfen einiges Licht auf die von Boutroux (Acta Math. 28) und Lindelöf über \(f(x)\) aufgestellten Sätze.
